Question

the perimeter of a rectangular plot is 180 m. if length is 54 m, find its breadth.

Answer 1

$2(54 + x) = 180 \\ 54 + x = \frac{180}{2} \\ 54 + x = 90 \\ x = 90 - 54 \\ x = 36 \\ breath \: is \: 36 \: cm$

Answer 2

Heya
Here is your answer
_____________________________________________________________

Perimeter of rectangular plot = 180 m

2(L+B) = 180 m

2(54+B) = 180

54 + B = 180/2

54 + B = 90

B = 90-54

B = 36

So the breadth is 36 m
