Answer: 2

SOLUTION 1 :

Ans = B

Area of trapezium = $\frac{1}{2}$ h(a+b) sq.units.

The sum of parallel sides of a trapezium is 16cm and height is 25cm. Then its area is...

1) 200
2) 205
3) 195
4) 202

Answer: 1

SOLUTION 1 :

Given,

a + b = 16 cm, h = 25 cm.

Area of trapezium = $\frac{1}{2}$ h(a+b)

= 1/2 25 x 16 ⁸

= 25 x 8

Area of trapezium = 200 cm²

In an isosceles trapezium

1) parallel sides are equal
2) non parallel sides are equal
3) parallel side = non parallel side
4) height = base

Answer: 2

SOLUTION 1 :

Ans = non parallel sides are equal

In an isosceles trapezium, non-parallel sides are equal.

The height of a trapezium whose sum of parallel sides is 40 cm and the area 90 cm² is

1) 4.5
2) 3.5
3) 5.5
4) 6.5

Answer: 1

SOLUTION 1 :

Given,

Area = 90 cm² a + b = 40

Area of trapezium = $\frac{1}{2}$ h (a+b)

= $\frac{1}{2}$ x h x 40 = 90 cm²

90 cm² = 1 / 2 x h x 40 ²⁰

h = $\frac{90}{20}$ = 4.5 cm.

The height of trapezium = 4.5 cm.

The area of trapezium is ______ sq.units.

(A) h(a+b) (B) $\frac{1}{2}$ h(a+b) (C) h(a+b) (D) $\frac{1}{2}$ h(a-b)

1) B
2) A
3) C
4) D

Answer: 1

SOLUTION 1 :

Ans = B

Area of trapezium = $\frac{1}{2}$ h(a+b) sq.units.

The sum of parallel sides of a trapezium is 18cm and height is 15cm. Then its area is...

1) 140
2) 130
3) 135
4) 137

Answer: 3

SOLUTION 1 :

Given,

a + b = 18 cm, h = 15 cm.

Area of trapezium = $\frac{1}{2}$ h(a+b)

= 1/2 15 x 18 ⁹

= 15 x 9

Area of trapezium = 135 cm²

In an isosceles trapezium

1) parallel side = non parallel side
2) non parallel sides are equal
3) height = base
4) parallel sides are equal

Answer: 2

SOLUTION 1 :

Ans = non parallel sides are equal

In an isosceles trapezium, non-parallel sides are equal.

The height of a trapezium whose sum of parallel sides is 10 cm and the area 110 cm² is

1) 23
2) 24
3) 22
4) 21

Answer: 3

SOLUTION 1 :

Given,

Area = 110 cm² a + b = 10

Area of trapezium = $\frac{1}{2}$ h (a+b)

= $\frac{1}{2}$ x h x 10 = 110 cm²

110 cm² = 1 / 2 x h x 10 ⁵

h = $\frac{110}{5}$ = 22 cm.

The height of trapezium = 22 cm.

The area of trapezium is ______ sq.units.

(A) h(a+b) (B) $\frac{1}{2}$ h(a+b) (C) h(a+b) (D) $\frac{1}{2}$ h(a-b)

1) B
2) C
3) A
4) D

Answer: 1

SOLUTION 1 :

Ans = B

Area of trapezium = $\frac{1}{2}$ h(a+b) sq.units.

10)

The sum of parallel sides of a trapezium is 18cm and height is 20cm. Then its area is...

1) 175
2) 182
3) 180
4) 185

Answer: 3

SOLUTION 1 :

Given,

a + b = 18 cm, h = 20 cm.

Area of trapezium = $\frac{1}{2}$ h(a+b)

= 1/2 20 x 18 ⁹

= 20 x 9

Area of trapezium = 180 cm²
