Question

Find the area of a rectangle whose breadth is 7 m and its perimeter is equal to that of a square
with side 12 m.​

Answer 1

Answer:

119m^2

Step-by-step explanation:

Since we know,

perimeter of a square = 4s

Therefore = 4 X 12 =48m

And perimeter of a Rectangle = 2(l+b)

So, 48m = 2(l+7)

48m = 2l+14

48 - 14 = 2l

34 = 2l

34/2 = l

17 = l

Now, area of a rectangle = l X b = 17 X 7 = 119m^2
