Question

The area of a rectangular lawn is 255m2 if it’s length is 15 m what is it’s perimeter

Answer 1

Given area=255 m²
Length=15 m

But.. Area=length*breadth
255=15*breadth
Breadth =255/15=17 m²

Perimeter =2(l+b)
=)2(15+17)
=)2*32
=)64 m

Answer 2

area=255m.sq
length=15m
area of rectangular lawn=l*b sq units
255=15*b
255=15b
15b=255
b=255/15
b=17 m
perimeter of a rectangular lawn=2(l+b )units
=2(15+17) units
=2(32)
=64m
