Question

There is a flowerbed that is in the shape of a trapezium.Its area is 700m2.The sum of ts upper base and lower base is 70m.Find its height. longman workbook 5A p42 *10

Answer 1

h = 16 m

Explanation:

Given that,

The area of a trapezium, A = 700 m²

The sum of the length of the parallel sides = 70 m

The area of a trapezium is given by :

`A=(1)/(2)* \text{sum of parallel sides}* height\\\\h=(2A)/(Sum)\\\\=(2* 700)/(70)\\\\=20\ m`

So, the height of the flower bed is 20 m.
