Question

the area of a rectangular lawn is 255 m square . If it's length is 15 m find its perimeter ?

Answer 1

Area of rectangle = 255m^2

Length = 15 m

So, breadth = area /length

= 255/15 = 17m

Now, 2(l +b) = 2( 15 +17)m

P = 2 ☓ 32m = 64 m

Hence perimeter is 64m

GIVEN : area of rectangular lawn = 255m
Its length = 15m
Its breadth = not given

We have to find the breadth of rectangular lawn

So now,

Area of rectangular lawn = L × B = 255m
255 = 15 × B
B = 255/15
B = 17m

So now find Perimeter

Perimeter of rectangular lawn = 2(L + B)
= 2(15 + 17)
= 2×32
= 64m

Therefore perimeter of rectangular lawn is 64m
