Question

What is the perimeter of the rectangle given below if each small square has side equal to 1 cm?

• A. 8 cm
• B. 18 cm
• C. 15 cm
• D. 16 cm

Answer 1

The correct option is D 16 cm

We can observe that we have a rectangle in the given image made up of squares.

Side length of each small square = 1 cm

Length of the rectangle = 5 $\times$ 1 = 5 cm

Breadth of the rectangle = 3 $\times$ 1 = 3 cm

Perimeter of any polygon is the sum of lengths of all its sides.

Therefore, perimeter of the rectangle
= 2(length + breadth)
= 2(5 + 3)
= 16 cm
