Question

the area of a rectangle is 540 cm² and its length is 36 cm find its width and perimeter​

Answer 1

Step-by-step explanation:

area of rectangle = length × breath

540 = 36 × b

540 /36 = b

breath= 15 cm

perimeter of rectangle = 2 ( length + breath)

= 2 ( 36 + 15 )

= 2 ×51

= 102 cm

Answer 2

Answer:

The Perimeter is 102 cm.

Step-by-step explanation:

Given :

Area of the rectangle = 540 cm²

Length = 36 cm

To find :

The width and perimeter

Solution :

Let the Width be y

★ Area = Length × Breadth

$\implies$ 540 = 36 × y

$\implies$ y = 540 ÷ 36

$\implies$ y = 15

Width = 15 cm

$\rule{300}{1.5}$

★ Perimeter = 2(Length + Width)

$\implies$ 2(36 + 15)

$\implies$ 72 + 30

$\implies$ 102 cm

$\therefore$ The Perimeter is 102 cm.
