• Separate Answer

• Surface Area

• Square Angle

Olivia is planning to build a garden in the shape of a parallelogram. She decides the garden will have base lengths of 8 units and a height of 5 units. The area of Olivia's garden will be (a)   square units.

• 40 square units

• 13 square units

• 26 square units

• 80 square units

Answer explanation

The area of a parallelogram is calculated by multiplying the base length by the height. In this case, 8 units * 5 units = 40 square units. Therefore, the correct answer is 40 square units.
