Answer:

P = 28cm

Step-by-step explanation:

The general formula for the perimeter of a rectangle is: 'P = 2L +2W' (L being the length and W being the width of the rectangle.)

Step 1: Substitute L = 7, W = 7 into the general formula.

P = 2(7) + 2(7)

Step 2: Solve!

P = 2 x 7 + 2 x 7

P = 14 + 14

P = 28

Step 3: Don't forget to add the units of measurement! (In this case 'cm')

Therefore, P = 28cm
