Area and Perimeter of Rectangles

The answer is 6.

When I want to find the perimeter of a rectangle, I add the lengths of all of the sides.

If I add all of the lengths of the sides of the rectangle, I solve the equation 1+1+2+2=6.

The answer is 6.

When I want to find the area of a rectangle, I multiply the lengths of the length and width.

If I multiply the length (3) by the width (2) of the rectangle, I solve the equation 2x3=6.

The answer is 40.

When I want to find the perimeter of a square, I add the lengths of all of the sides. Each side of a square is the same length.

If I add all of the lengths of the sides of the square, I solve the equation 10+10+10+10=40.

The answer is 32.

When I want to find the area of a rectangle, I multiply the length and the width.

If I multiply the length (8) and and the width (4), I solve the equation 8x4=32.

The answer is 22.

When I want to find the perimeter of a rectangle, I add the lengths of all of the sides.

If I add all of the lengths of the sides of the rectangle, I solve the equation 5+5+6+6=22.

The answer is 1,521.

When I want to find the area of a square, I multiply the length and width. All sides of a square are equal, so the length and width are the same.

If I multiply all of the length (39) and width (39), I solve the equation 39x39=1,521.

The answer is 2.

When I want to find the length of a missing side of a rectangle and I know the length of one side and the area of the rectangle, I need to divide the area by the length of the side.

I know that doing this will give me the length of the missing side because it's the opposite of how I find the area when I know the length and width.

If I divide the area (8) by the length of the known side (4), I solve the equation 8 divided by 4 equals 2.

The answer is 8.

When I know the perimeter of a rectangle and the length of two of the sides, I can add the lengths of the known sides and subtract them from the perimeter. This will tell me what length remains.

Then, I need to divide this length by 2 because there are 2 equal sides that are sharing this value.

If I add the two known sides (5 and 5), I get 10. If I subtract 10 from the perimeter (26), I solve the equation 26-10=16.

The length shared by the two unknown sides is 16. When I divide 16 by 2, I learn that each unknown side has a length of 8 inches.

The answer is 8.

When I need to find the area of a rectangle, I multiply the length and width.

If I multiply the length (2) and width (4) of this rectangle, I solve the equation 2x4=8.

The answer is 5.

When I need to find the length of an unknown side of a rectangle but I know the perimeter and the length of 2 other sides, I can add the lengths of the two known sides and then subtract that total from the perimeter.

Then, I need to divide this remaining length by 2 to find the length of 1 of the missing sides.

If I add the length of the known sides of the rectangle (6 and 6), I get 12. When I subtract 12 from the perimeter (22), I get a difference of 10.

If I divide the remaining length of 10 by 2, I learn that each of the unknown sides are 5 inches long.
