Find the Perimeter and area of each square and rectangle. On my actual paper I have the cm and in behind the numbers along with the area's squared sign I just didn't know how to put that on here.
1. L2 W3 A=6 P=10
2. L1 W1 A=1 P=4
3. L7 W1 A=7 P=16
4. L7 W7 A=49 P=28
5. L6 W4 A=24 P=20
6. L12 W9 A=108 P=42
7. L3 W3 A=9 P=12
8. L15 W15 A=225 P=60
9. L11 W 8 1/2 A=93.5 P=39
10. L14 1/2 W12 1/4 A=278.15 P=53.6
11. L2.4 W2.4 A=5.76 P=9.6
12. L5.8 W 5.8 A=33.64 P=23.2

You indicate "square" by using ^2 -- example: 6^2 cm (the area for #1).
They all look correct to me.
thank you
You're welcome.

To find the perimeter and area of each square and rectangle, you will need to use the formulas for perimeter and area.
Perimeter of a square: The perimeter of a square is found by multiplying the length of one of its sides by 4.
Area of a square: The area of a square is found by squaring the length of one of its sides.
Perimeter of a rectangle: The perimeter of a rectangle is found by adding the lengths of all four sides.
Area of a rectangle: The area of a rectangle is found by multiplying the length by the width.
I will provide the calculations for each of the given dimensions.
1. For a square with side length L=2 cm and width W=3 cm:
Area = L^2 = 2^2 = 4 square cm
Perimeter = 2(L + W) = 2(2 + 3) = 10 cm
2. For a square with side length L=1 cm and width W=1 cm:
Area = L^2 = 1^2 = 1 square cm
Perimeter = 2(L + W) = 2(1 + 1) = 4 cm
3. For a rectangle with length L=7 cm and width W=1 cm:
Area = L * W = 7 * 1 = 7 square cm
Perimeter = 2(L + W) = 2(7 + 1) = 16 cm
4. For a square with side length L=7 cm and width W=7 cm:
Area = L^2 = 7^2 = 49 square cm
Perimeter = 2(L + W) = 2(7 + 7) = 28 cm
5. For a rectangle with length L=6 cm and width W=4 cm:
Area = L * W = 6 * 4 = 24 square cm
Perimeter = 2(L + W) = 2(6 + 4) = 20 cm
6. For a rectangle with length L=12 cm and width W=9 cm:
Area = L * W = 12 * 9 = 108 square cm
Perimeter = 2(L + W) = 2(12 + 9) = 42 cm
7. For a square with side length L=3 cm and width W=3 cm:
Area = L^2 = 3^2 = 9 square cm
Perimeter = 2(L + W) = 2(3 + 3) = 12 cm
8. For a square with side length L=15 cm and width W=15 cm:
Area = L^2 = 15^2 = 225 square cm
Perimeter = 2(L + W) = 2(15 + 15) = 60 cm
9. For a rectangle with length L=11 cm and width W=8.5 cm:
Area = L * W = 11 * 8.5 = 93.5 square cm
Perimeter = 2(L + W) = 2(11 + 8.5) = 39 cm
10. For a rectangle with length L=14.5 cm and width W=12.25 cm:
Area = L * W = 14.5 * 12.25 = 178.0625 square cm
Perimeter = 2(L + W) = 2(14.5 + 12.25) = 53.6 cm
11. For a square with side length L=2.4 cm and width W=2.4 cm:
Area = L^2 = 2.4^2 = 5.76 square cm
Perimeter = 2(L + W) = 2(2.4 + 2.4) = 9.6 cm
12. For a rectangle with length L=5.8 cm and width W=5.8 cm:
Area = L * W = 5.8 * 5.8 = 33.64 square cm
Perimeter = 2(L + W) = 2(5.8 + 5.8) = 23.2 cm
Note: Number 12 is a duplicate, I assume you meant to provide different dimensions here.
