Question

the area of a trapezium is 1100 m2. the distance between two parallel sides is 20 m and one of the parallel sides is 70 m. find the length of the other parallel side.

Answer 1

Answer:

Other parallel side (b) = 40m

Explanation:

Let a,b are two parallel sides.

a = 70m ,

Distance between two

parallel sides (h) = 20m

Area (A)= 1100m²

=> [(a+b)h]/2 = 1100

=> [(70+b)20]/2 = 1100

=> (70+b)10 = 1100

=> 70+b = 1100/10

=> b = 110 - 70

=> b = 40 m

Therefore,

Other parallel side (b) = 40m
