cm²

Answer:_______________

The area of a trapezium whose altitudes and parallel sides are given below:

altitude = 42 cm, parallel sides = 2 cm and 8 cm.

Answer: 210 cm²

SOLUTION 1 :

Given:

h = 42 cm, a = 2, b = 8, Area =

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

= $\frac{1}{2}$ x 42 x (2 + 8)

= 1/ 2 x 42 ²¹x 10

Area of trapezium = 210 cm².

The area of a trapezium whose altitudes and parallel sides are given below:

altitude = 30 cm, parallel sides = 9 cm and 4.5 cm.

Answer: 202.5 cm²

SOLUTION 1 :

Given:

h = 30 cm, a = 9, b = 4.5, Area =

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

= $\frac{1}{2}$ x 30 x (9 + 4.5)

= 1/ 2 x 30 ¹⁵x 13.5

= 15 x 13.5

Area of trapezium = 202.5 cm².

The area of a trapezium whose altitudes and parallel sides are given below:

altitude = 14 cm, parallel sides = 5.5 cm and 7.5 cm.

Answer: 91 cm²

SOLUTION 1 :

Given:

h = 14 cm, a = 5.5, b = 7.5, Area =

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

= $\frac{1}{2}$ x 14 x (5.5 + 7.5)

= 1/ 2 x 14 ⁷x 13

= 7 x 13

Area of trapezium = 91 cm².

The area of a trapezium whose altitudes and parallel sides are given below:

altitude = 44 cm, parallel sides = 4 cm and 7 cm.

Answer: 242 cm²

SOLUTION 1 :

Given:

h = 44 cm, a = 4, b = 7, Area =

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

= $\frac{1}{2}$ x 44 x (4 + 7)

= 1/ 2 x 44 ²²x 11

Area of trapezium = 242 cm².

The area of a trapezium whose altitudes and parallel sides are given below:

altitude = 28 cm, parallel sides = 8 cm and 6.5 cm.

Answer: 203 cm²

SOLUTION 1 :

Given:

h = 28 cm, a = 8, b = 6.5, Area =

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

= $\frac{1}{2}$ x 28 x (8 + 6.5)

= 1/ 2 x 28 ¹⁴x 14.5

= 14 x 14.5

Area of trapezium = 203 cm².

The area of a trapezium whose altitudes and parallel sides are given below:

altitude = 20 cm, parallel sides = 5.5 cm and 6.5 cm.

Answer: 120 cm²

SOLUTION 1 :

Given:

h = 20 cm, a = 5.5, b = 6.5, Area =

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

= $\frac{1}{2}$ x 20 x (5.5 + 6.5)

= 1/ 2 x 20 ¹⁰x 12

= 10 x 12

Area of trapezium = 120 cm².

The area of a trapezium whose altitudes and parallel sides are given below:

altitude = 34 cm, parallel sides = 2 cm and 9 cm.

Answer: 187 cm²

SOLUTION 1 :

Given:

h = 34 cm, a = 2, b = 9, Area =

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

= $\frac{1}{2}$ x 34 x (2 + 9)

= 1/ 2 x 34 ¹⁷x 11

Area of trapezium = 187 cm².

The area of a trapezium whose altitudes and parallel sides are given below:

altitude = 10 cm, parallel sides = 6 cm and 6.5 cm.

Answer: 62.5 cm²

SOLUTION 1 :

Given:

h = 10 cm, a = 6, b = 6.5, Area =

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

= $\frac{1}{2}$ x 10 x (6 + 6.5)

= 1/ 2 x 10 ⁵x 12.5

= 5 x 12.5

Area of trapezium = 62.5 cm².

The area of a trapezium whose altitudes and parallel sides are given below:

altitude = 18 cm, parallel sides = 4.5 cm and 7.5 cm.

Answer: 108 cm²

SOLUTION 1 :

Given:

h = 18 cm, a = 4.5, b = 7.5, Area =

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

= $\frac{1}{2}$ x 18 x (4.5 + 7.5)

= 1/ 2 x 18 ⁹x 12

= 9 x 12

Area of trapezium = 108 cm².

10)
