Question

The perimeter of a square is 16 cm. Find the length of its diagonal.​

Answer 1

Step-by-step explanation:

method 1

The formula for the perimeter of a square is 4L, where L is length.

So to answer this question we'd have to do this:

4L = 16

L = 16/4

L = 4

method 2

A square is a plane figure having 4 equal sides and 4 equal angles. The perimeter of a square is 4 x length of 1 side. So, in this case, P = 4 x side. 16 = 4 x side, so side = 16/4 = 4 cm.
