Question

Half of perimeter of rectangular garden whose length 4 centimetre more than its width is 36 cm find length and breadth

Answer 1

let the width be x.
hence, the length will be (x+4)

A.T.Q
1/2x (2(x+x+4))= 36
1/2x (4x+8)= 36
4x+8= 36x2
4x= 72-8
x= 64/4
x= 16

hence, width=x=16cm
length=x+4=20 cm
