Answer 1

Given :

Perimeter of a rectangle is 120 centimeters . The length is 20 cm.

To find :

Breadth of rectangle and area of rectangle.

Solution :

Perimeter = 120 cm

Length = 20 cm

             ∵ Perimeter of rectangle = 2(Length + Breadth)

Now atq,

⇒ 120 = 2(20 + Breadth)

⇒ 120/2 = 20 + Breadth

⇒ 60 = 20 + Breadth

⇒ 60 - 20 = Breadth

⇒ 40 = Breadth

⇒ Breadth = 40 cm.

∴ Breadth of rectangle = 40 cm.

Now area of rectangle :

                 ∵ Area of rectangle = Length * Breadth

Now atq,

⇒ Area of rectangle = 20 × 40

⇒ Area of rectangle = 800 cm²

∴ Area of rectangle = 800 cm²

Answer 2

Answer:

A=800cm²
