Question

The area of the trapezium shaped field is 480 m², the height is 15 m and one of the parallel side is 20 m. Find the other side?

Answer 1

Answer:

Step-by-step explanation:

let the other parallel side be 'a'

area of trapezium= 1/2(a+b)*h

480m^2= 1/2(a+20)*15

480m^2/15 = 1/2a+ 10

32=a/2+10

32 = a+20/2

64= a + 20

a = 44 answer
