Question

Help please! :)

Find the area of the following shapes. Remember to make your method clear and give the final
answer with the correct units.

Answer 1

a.

80 cm²

b.

28 cm²

Explanation:

a.

This is a parallelogram. We use the following formula to calculate the area of a parallelogram:

b × h

• b: base, h: height
• Write the equation using the given values.

10 × 8 = 80

• The area is expressed in square units, so the answer is 80 cm².

b.

This is a trapezoid. We use the following formula to calculate the area of a trapezoid:

(a+b)÷2×h

• a and b are bases, and h is the height.

(5+9) ÷ 2 × 4 = 28

• Again, the area is expressed in square units, so the answer is 28 cm².
