A parallelogram is a four-sided figure (quadrilateral) where opposite sides are parallel and equal in length.

Front

What is the formula for the area of a rectangle?

Back

A = l × w (Area = length × width)

Front

What is the formula for the area of a triangle?

Back

A = (b × h) / 2 (Area = base × height divided by 2)

Front

What is the formula for the area of a trapezoid?

Back

A = (h)(b1 + b2) / 2 (Area = height × (base1 + base2) divided by 2)

Front

What is the area of a figure with a base of 4 units and a height of 3 units?

Back

A = (4 × 3) / 2 = 6 units² (Area of a triangle)

Front

What is the area of a rectangle with a length of 5 units and a width of 3 units?

Back

A = 5 × 3 = 15 units²

Front

Which number is not needed to solve for area? 300 ft, 19 ft, 15 ft, 24 ft
