Question

if the area of a trapezium is 28 cm2 and one of its parallel sides is 6cm ,find the other parallel side if its altitude is 4cm

Answer 1

Heya frnd,

Given that

Area = 28 cm^2

First parallel sides = 6 cm

Altitude = 4 cm

Let the other parallel sides be x cm.

Then,

according to question,

Area of a trapezium = 1/2 × sum of parallel sides × altitude

28 = 1/2 (6 + x) × 4

28/4 = 1/2 (6 + x)

7 × 2 = 6 + x

14 = 6 + x

- x = 6 - 14

- x = - 8

x = 8

Hence, the other sides of the trapezium is 8 cm.
