A good way to remember Pi would be 3.1459. You can remember it in a song or just simply repeat it until you can memorize it.
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
