Front

If a rectangle has a length of 10 and a width of 5, what is its area?

Back

Area = 10 x 5 = 50

Front

If a rectangle has a perimeter of 30 and one side is 10, what is the length of the other side?

Back

Perimeter = 2 x (Length + Width) => 30 = 2 x (10 + Width) => Width = 5

Front

What is the perimeter of a square with a side length of 4?

Back

Perimeter = 4 x 4 = 16

Front

What is the area of a square with a side length of 4?

Back

Area = 4 x 4 = 16

Front

If a rectangle has a length of 8 and a width of 3, what is its perimeter?

Back

Perimeter = 2 x (8 + 3) = 22

Front

What is the relationship between area and perimeter?

Back
