Question

Each side of a square has a length of 45. what is the perimeter of this square?

Answer 1

Solution 19:

Side of square = 45 cm

∴ Perimeter = 4a = 4 × 45 cm = 180 cm

Or Perimeter of rectangle = 180 cm

Length of rectangle = 50 cm

∴ Breadth = P/2 – l = 180/2 – 50

= 90 – 50 = 40 cm

Answer 2

180

Explanation:

A square has 4 congruent sides.

Congruent sides have the same length.

perimeter = 4 × side length

perimeter = 4 × 45

perimeter = 180
