Answer 2

Solution!!

The length and breadth of the rectangle are given. We have to find the area and the perimeter. There are two formulae you can remember.

→ Perimeter = 2(Length + Breadth)

→ Area = Length × Breadth

These two formulae are used to find the perimeter and the area of a rectangle, respectively.

Length = 40 cm

Breadth = 12 cm

Let's find out the perimeter first.

Perimeter = 2(Length + Breadth)

Perimeter = 2(40 cm + 12 cm)

Perimeter = 2(52 cm)

Perimeter = 104 cm

We have the perimeter. Let's calculate the area.

Area = Length × Breadth

Area = 40 cm × 12 cm

Area = 480 cm²
