Question

The length and area of a rectangle is 12m and 60 sq m . Find the breadth and perimeter of the rectangle.

Answer 1

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

Answer 2

$\mathtt{\huge{\underline{\pink{Answer :-}}}}$

Given :-

• The length of a rectangle is 12m.

• The area of a rectangle is 60 sq m.

To Find :-

• The breadth of the rectangle.

• The perimeter of the rectangle.

Solution :-

We know that , area of a rectangle is l × b.

The area of a rectangle is 60 sq m.(Given)

l × b = 60

Where, ( l ) length of a rectangle is 12m.

➝ 12 × b = 60

➝ b = $\cancel{\dfrac{60}{12}}$

➝ b = 5 m

The breadth of the rectangle is 5 meter.

The perimeter of the rectangle is 2 ( l + b ).

➝ 2 ( 12 + 5 )

➝ 2 × 17

➝ 34m

Hence, The perimeter of the rectangle is 34m .
