Area of squares, rectangles, and parallelograms

Front

What is the formula for the area of a rectangle?

Back

The area of a rectangle is calculated using the formula: Area = length × width.

Front

What is the formula for the area of a square?

Back

The area of a square is calculated using the formula: Area = side × side or Area = side².

Front

What is the formula for the area of a parallelogram?

Back

The area of a parallelogram is calculated using the formula: Area = base × height.

Front

If a rectangle has a length of 8ft and a width of 5ft, what is its area?

Back

Area = 8ft × 5ft = 40ft².

Front

If a square has a side length of 6cm, what is its area?

Back

Area = 6cm × 6cm = 36cm².

Front

If a parallelogram has a base of 10m and a height of 4m, what is its area?

Back

Area = 10m × 4m = 40m².

Front

What is the relationship between the base and height of a parallelogram in calculating its area?

Back

The area of a parallelogram depends on the length of the base and the perpendicular height from the base to the opposite side.

Front

How do you find the height of a parallelogram if you know the area and the base?

Back

Height can be found using the formula: Height = Area ÷ base.

Front

What is the area of a rectangle with a length of 12in and a width of 3in?

Back

Area = 12in × 3in = 36in².

Front

If a square has an area of 49m², what is the length of one side?

Back

Side length = √49m² = 7m.
