Question

The area of a Trapezium is 660 CM square and the length of one of the parallel side is 28 CM if its height is 30 centimetre find the length of the Other parallel side

Answer 1

We know that the area of a trapezium

½×(sum of parallel sides)×height

then,

height = 30cm
area = 660cm²
one side = 28cm
let another side = x

then.

½×(28+x)×30 = 660

=> 14+x/2 = 22

=>x/2 = 22-14

=>x = 8×2

=>x = 16

Then the length of another parallel side of trapezium is 16cm.

Answer 2

The other parallel side of the trapezium is 16 cm.

Given: Area of trapezium is 660 sq.cm height is 30cm anf one of the parallel side is 28 cm.

To Find: Length of other parallel side of the trapezium

Solution:

Area of the trapezium is 660 sq.cm

Let other parallel side of the trapezium is x

Height of trapezium is 30cm

Area of trapezium is $\frac{1}{2}*h*$(sum of parallel side)

660 = 1/2×30×(28+x)

44 = 28+x

x = 16cm.

Hence,the length of the other parallel side of the trapezium is 16 cm.
