Answer 1

Answer:

The length of rectangular plot be X+5m

The breadth of rectangular plot be Xm

The perimeter of rectangular plot is 142m

We know that,

Perimeter of rectangular plot=lxb

Hence,

lxb = 142

X+5xX. =142

2X+5. =142

2X. =142-5

2X. =137

X. =137/2

X. =68.5

The breadth of rectangular plot is 68.5m

The length of rectangular plot is 73.5m
