What is the formula for the AREA of a TRIANGLE?

• A = bh

• A = 1/2 bh

• A = LW

What is the formula for the AREA of a RECTANGLE? (2 options are possible!)

• A = LW

• A = bh

• A = 1/2 bh

What is the formula for the AREA of a trapezoid?

• A = LW

• A = bh

• A = 1/2 bh

• A = 1/2 h(b₁ + b₂)

What is the AREA of a parallelogram?

• A = LW

• A = bh

• A = 1/2 bh

• A = 1/2 h(b₁ + b₂)

Identify the shapes in the composite figure (choose 2 options)

• Circle

• Trapezoid

• Triangle

• Rectangle

• Parallelogram

Choose the (2) AREAs to make the composite figure.

• Triangle = 2 units X 8 units = 16 squared units

• Triangle = 1/2(2 units X 8 units) = 8 squared units

• 2 Rectangles = (8 units X 6 units) - (2 units X 5 units)

• 2 Rectangles = (8 units X 6 units) + (2 units X 5 units)
