Front

If a rectangle has a length of 5 units and a width of 3 units, what is its area?

Back

Area = 5 × 3 = 15 square units.

Front

If a rectangle has a perimeter of 20 units and one side is 6 units, what is the length of the other side?

Back

Perimeter = 2 × (length + width) => 20 = 2 × (6 + width) => width = 4 units.

Front

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

Back

Area = side × side = 4 × 4 = 16 square units.

Front

What shape has an area of 18 square units and a length of 6 units?

Back

Width = Area ÷ Length = 18 ÷ 6 = 3 units.

Front

What is the difference between area and perimeter?

Back

Area measures the space inside a shape, while perimeter measures the distance around it.

Front

If a rectangle has a length of 10 units and a width of 2 units, what is its perimeter?

Back
