Question

If the perimeter of a rectangle is 36 meters and the length is 12 meters, then what will be the area of ​​that rectangle?

Answer 1

Answer:

the perimeter of a rectangle = 36 m

2(l+ b ) = 36m

2 ( 12m + b) = 36 m

12m + b = 36m/2

12m + b = 18m

b = 18m-12m

b= 6m

therefore,

the area of rectangle= l×b

= 12m × 6m

= 72m^2 ans.
