Area of a rhombus is 115 cm². one of its diagonal is 2 cm. Find the length of the other diagonal.

Answer:_______________

Area of a rhombus is 69 cm². one of its diagonal is 13 cm. Find the length of the other diagonal.

Answer: 138 cm

SOLUTION 1 :

Given :

Area = 69 cm²

diagonal(d1) = 13cm

Area of the rhombus = $\frac{1}{2}$ x d1 x d2 sq.uni

69 = $\frac{1}{2}$ x 13 x d2

(2 x $\frac{69)}{13}$ = d2

$\frac{138}{13}$ = d2

10.6 cm = d2

The length of the other diagonal = 10.6cm

Area of a rhombus is 144 cm². one of its diagonal is 8 cm. Find the length of the other diagonal.

Answer: 288 cm

SOLUTION 1 :

Given :

Area = 144 cm²

diagonal(d1) = 8cm

Area of the rhombus = $\frac{1}{2}$ x d1 x d2 sq.uni

144 = $\frac{1}{2}$ x 8 x d2

(2 x $\frac{144)}{8}$ = d2

$\frac{288}{8}$ = d2

36.0 cm = d2

The length of the other diagonal = 36.0cm

Area of a rhombus is 55 cm². one of its diagonal is 11 cm. Find the length of the other diagonal.

Answer: 110 cm

SOLUTION 1 :

Given :

Area = 55 cm²

diagonal(d1) = 11cm

Area of the rhombus = $\frac{1}{2}$ x d1 x d2 sq.uni

55 = $\frac{1}{2}$ x 11 x d2

(2 x $\frac{55)}{11}$ = d2

$\frac{110}{11}$ = d2

10.0 cm = d2

The length of the other diagonal = 10.0cm

Area of a rhombus is 105 cm². one of its diagonal is 3 cm. Find the length of the other diagonal.

Answer: 210 cm

SOLUTION 1 :

Given :

Area = 105 cm²

diagonal(d1) = 3cm

Area of the rhombus = $\frac{1}{2}$ x d1 x d2 sq.uni

105 = $\frac{1}{2}$ x 3 x d2

(2 x $\frac{105)}{3}$ = d2

$\frac{210}{3}$ = d2

70.0 cm = d2

The length of the other diagonal = 70.0cm

Area of a rhombus is 147 cm². one of its diagonal is 11 cm. Find the length of the other diagonal.

Answer: 294 cm

SOLUTION 1 :

Given :

Area = 147 cm²

diagonal(d1) = 11cm

Area of the rhombus = $\frac{1}{2}$ x d1 x d2 sq.uni

147 = $\frac{1}{2}$ x 11 x d2

(2 x $\frac{147)}{11}$ = d2

$\frac{294}{11}$ = d2

26.7 cm = d2

The length of the other diagonal = 26.7cm

Area of a rhombus is 75 cm². one of its diagonal is 8 cm. Find the length of the other diagonal.

Answer: 150 cm

SOLUTION 1 :

Given :

Area = 75 cm²

diagonal(d1) = 8cm

Area of the rhombus = $\frac{1}{2}$ x d1 x d2 sq.uni

75 = $\frac{1}{2}$ x 8 x d2

(2 x $\frac{75)}{8}$ = d2

$\frac{150}{8}$ = d2

18.8 cm = d2

The length of the other diagonal = 18.8cm

Area of a rhombus is 55 cm². one of its diagonal is 5 cm. Find the length of the other diagonal.

Answer: 110 cm

SOLUTION 1 :

Given :

Area = 55 cm²

diagonal(d1) = 5cm

Area of the rhombus = $\frac{1}{2}$ x d1 x d2 sq.uni

55 = $\frac{1}{2}$ x 5 x d2

(2 x $\frac{55)}{5}$ = d2

$\frac{110}{5}$ = d2

22.0 cm = d2

The length of the other diagonal = 22.0cm

Area of a rhombus is 64 cm². one of its diagonal is 12 cm. Find the length of the other diagonal.

Answer: 128 cm

SOLUTION 1 :

Given :

Area = 64 cm²

diagonal(d1) = 12cm

Area of the rhombus = $\frac{1}{2}$ x d1 x d2 sq.uni

64 = $\frac{1}{2}$ x 12 x d2

(2 x $\frac{64)}{12}$ = d2

$\frac{128}{12}$ = d2

10.7 cm = d2

The length of the other diagonal = 10.7cm

Area of a rhombus is 125 cm². one of its diagonal is 8 cm. Find the length of the other diagonal.

Answer: 250 cm

SOLUTION 1 :

Given :

Area = 125 cm²

diagonal(d1) = 8cm

Area of the rhombus = $\frac{1}{2}$ x d1 x d2 sq.uni

125 = $\frac{1}{2}$ x 8 x d2

(2 x $\frac{125)}{8}$ = d2

$\frac{250}{8}$ = d2

31.3 cm = d2

The length of the other diagonal = 31.3cm

Area of a rhombus is 115 cm². one of its diagonal is 2 cm. Find the length of the other diagonal.

Answer: 230 cm

SOLUTION 1 :

Given :

Area = 115 cm²

diagonal(d1) = 2cm

Area of the rhombus = $\frac{1}{2}$ x d1 x d2 sq.uni

115 = $\frac{1}{2}$ x 2 x d2

(2 x $\frac{115)}{2}$ = d2

$\frac{230}{2}$ = d2

115.0 cm = d2

The length of the other diagonal = 115.0cm
