Question

Find the perimeter of figure given below

Answer 1

Answer:

$\mathsf\red{Perimeter \: of \: rectangle \: = \: 2(l+b)}$

$\mathsf\red{Given}$

$\mathsf{Length \: = \: 7x-2y}$

$\mathsf{breadth \: = \: 7(x+y) \: = \: 7x+7y}$

so

$\mathsf\red{Perimeter \: of \: rectangle \: = \: 2(l+b)}$

$\mathsf{Perimeter \: of \: rectangle \: = \: 2(7x-2y+7x+7y)}$

$\mathsf{Perimeter \: of \: rectangle \: = \: 2(14x+5y)}$

$\mathsf{Perimeter \: of \: rectangle \: = \: 28x+10y}$

$\mathsf\red{\therefore \: Perimeter \: of \: rectangle \: = \: 28x+10y}$
