Question

The parallel sides of a traperium are in the ratio 2:3, its height is 20cm and area is 500 cm ² find the length of the parallel sides​

Answer 1

Step-by-step explanation:

Now,

Area of trapezium=

1/2[sum of parallel sides×height]

1/2[(2x+3x)×20]= 500 cm^2

1/2[5x×20]= 500cm^2

5x=(500×2)÷20

x=(500×2)÷(20×5)

x=1000÷100

x=10

2x=2(10)=20. 3x=3(10)=30.

Hence sides are 20cm and 30cm
