Question

The length of a rectangular ground is 12m and its area is 108m square find its perimeter​

Answer 1

Answer:42 m

Explanation:

First find the missing side in the area by dividing both sides by 12. 108 divided by 12 equals 9. Then take that nine and use it to fill in the two missing sides of the rectangle. Now the length plus the width is 2(12) + 2(9) = 42

Answer 2

42

Explanation:

area =
`l` ×
`w`

108m^2 = 12 ×
`w`

`w=(108)/(12)`

`w=9`

2
`l` + 2
`w` = perimeter

2(12) + 2(9) = perimeter

24 + 18 = perimeter

perimeter = 42
