Question

1. Find the perimeter of a rectangle field which is 36 cm long and 24 m wide.

Answer 1

Given:

A rectangle field with

• Length = 36 cm
• Breath = 24 cm

What To Find:

We have to find the perimeter of the rectangle field.

How To Find:

To find it we will use,

• Perimeter = 2(l + b)

Where

• l = length
• b = breadth

Solution:

Using the formula,

⇒ Perimeter = 2(l + b)

Substitute the values,

⇒ Perimeter = 2(36 + 24)

Solve the brackets,

⇒ Perimeter = 2 × 60

Multiply 2 by 60,

⇒ Perimeter = 120 cm

∴ Thus, the perimeter of rectangular field is 120 cm.

Verification:

Using the formula,

⇒ Perimeter = 2(l + b)

Substitute the values,

⇒ 120 cm = 2(36 cm + 24 cm)

Solve the brackets,

⇒ 120 cm = 2 × 60 cm

Multiply 2 by 60,

⇒ 120 cm = 120 cm

∴ LHS = RHS

∴ Hence, verified.
