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 22cm and height is 20cm. Then its area is...

1) 222
2) 215
3) 225
4) 220

Answer: 4

SOLUTION 1 :

Given,

a + b = 22 cm, h = 20 cm.

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

= 1/2 20 x 22 ¹¹

= 20 x 11

Area of trapezium = 220 cm²

The height of a trapezium whose sum of parallel sides is 40 cm and the area 190 cm² is

1) 11.5
2) 9.5
3) 8.5
4) 10.5

Answer: 2

SOLUTION 1 :

Given,

Area = 190 cm² a + b = 40

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

= $\frac{1}{2}$ x h x 40 = 190 cm²

190 cm² = 1 / 2 x h x 40 ²⁰

h = $\frac{190}{20}$ = 9.5 cm.

The height of trapezium = 9.5 cm.

In an isosceles trapezium

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

Answer: 1

SOLUTION 1 :

Ans = non parallel sides are equal

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

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 20cm and height is 20cm. Then its area is...

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

Answer: 3

SOLUTION 1 :

Given,

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

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

= 1/2 20 x 20 ¹⁰

= 20 x 10

Area of trapezium = 200 cm²

The height of a trapezium whose sum of parallel sides is 20 cm and the area 90 cm² is

1) 9
2) 10
3) 11
4) 8

Answer: 1

SOLUTION 1 :

Given,

Area = 90 cm² a + b = 20

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

= $\frac{1}{2}$ x h x 20 = 90 cm²

90 cm² = 1 / 2 x h x 20 ¹⁰

h = $\frac{90}{10}$ = 9 cm.

The height of trapezium = 9 cm.

In an isosceles trapezium

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

Answer: 1

SOLUTION 1 :

Ans = non parallel sides are equal

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

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) D
2) B
3) A
4) C

Answer: 2

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 24cm and height is 5cm. Then its area is...

1) 55
2) 62
3) 60
4) 65

Answer: 3

SOLUTION 1 :

Given,

a + b = 24 cm, h = 5 cm.

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

= 1/2 5 x 24 ¹²

= 5 x 12

Area of trapezium = 60 cm²
