Question

The length of a rectangle is thrice its breadth. the area of the rectangle is 48 sq m. find its perimeter

Answer 1

perimeter of rectangle is 32 m

Answer 2

Given

Length of rectangle ⇒ 12 m

Area of rectangle ⇒ 60 m²

_______________________________

To Find

Breadth of rectangle

Perimeter of Rectangle

_______________________________

Solution

Area of Rectangle ⇒ Length × Breadth

Length ⇒ 12 m

Breadth ⇒ x m

Breadth ⇒ Area ÷ Length

Breadth ⇒ 60 ÷ 12

Breadth ⇒ 5

∴ Breadth = 5 m

Perimeter of Rectangle ⇒ 2 (Length + Breadth)

Length ⇒ 12 m

Breadth ⇒ 5 m

Perimeter of Rectangle ⇒ 2 (12 + 5)

Perimeter of Rectangle ⇒ 2 (17)

Perimeter of Rectangle ⇒ 34

∴ Perimeter of Rectangle = 34 m
