Question

perimeter of a rectangle is 72 cm.if it's length is 24 cm then what will be it's breadth.​

Answer 1

$\sf \Large Solution!!$

Perimeter = 72 cm

Length = 24 cm

Perimeter = 2(Length + Breadth)

72 cm = 2(24 cm + Breadth)

$\sf \dfrac{72\:cm}{2}$= 24 cm + Breadth

36 cm = 24 cm + Breadth

Breadth = 36 cm - 24 cm

Breadth = 12 cm
