Question

The area of a trapezium is 132 cm2 and its height is 12 cm. The parallel sides of the trapezium are in the ratio 3:8. Find the lengths of the parallel sides

Answer 1

Answer:

6 and 16

Step-by-step explanation:

Area of trapezium=1/2×(sum of || sides)×height

let the first parallel sides=3x

let the second parallel sides=8x

A/Q

132cm²=1/2×(3x+8x)×12

132cm²=6×11x

66x=132cm²

x=132cm²÷66

x=2cm

• first parallel sides=3×2=6
• second parallel sides=8×2=16
