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

Answer 1

Answer:

Step-by-step explanation:

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.

Answer 2

A trapezium or a trapezoid is a quadrilateral with a pair of parallel sides. A parallelogram may also be called a trapezoid as it has two parallel sides. The pair of parallel sides is called the base while the non-parallel sides are called the legs of the trapezoid.
