Question

A square has an area of 196 square centimetres.

What is the perimeter?

Worked Solution

Let x\large x = length of 1 side
x\large x2^2 = 196
x\large x = 196\sqrt{196}
= 14 cm

∴\therefore Perimeter = 4 ×\times 14
= 56 cm

A square has an area of 225 square centimetres.

What is the perimeter?

Worked Solution

Let x\large x = length of 1 side
x\large x2^2 = 225
x\large x = 225\sqrt{225}
= 15 cm

∴\therefore Perimeter = 4 ×\times 15
