Question

Find the length of a rectangular park whose area is 204 square metres and breadth is 12 metres. ​

Answer 1

Breadth of the park is 12 m

and the area is 204 m^2

Let the length be l

Area of a rectangle = 2 (l+b)

= 204 m^2 = 2 (l+12)

= 204 = 2l + 24

= 204 - 24 = 2l

= 180 = 2l

therefore, length = 180/2 = 90 m answer.

Hope it helps you DEAR ❤

Answer 2

Answer:

Breadth of the park=12 m

area is=204 m^2

Let the length be l

Area of a rectangle=2×(L+B)

=204 m^2=2 (l+12)

=204=2l+24

=204-24=21

=180=21

Therefore,

Length=180/2=90m
