Question

Calculate the length of other side of trapezium is the area of 24 cm square the distance between its parallel sides 4cm and one of the sides is 7 cm

Answer 1

area of the trapezium =24 cm^2
distance between the parallel sides = 4 cm
one of the side be 7 cm
let the EC side be x m
so,
∆ BEC is a right angle ∆
so
7^2 =4^2 + x^2
49 = 16 + x^2
49-16=x^2
25 = x^2
x =√25 =5 cm
