Finding Area of Triangles, Parallelograms, Trapezoids

What is the area of this parallelogram?

• 38cm²

• 14cm²

• 35cm²

• 30cm²

What does area mean?

• the distance around a shape

• half the distance around a shape

• the amount of space outside a shape

• the amount of space inside a shape

Why does the trapezoid NOT fall under the category of parallelograms?

• All parallelograms have 4 sides; trapezoids have more than 4 sides.

• All parallelograms have right angles; trapezoids do not have any right angles.

• All parallelograms have perpendicular sides; trapezoids do not have any perpendicular sides.

• All parallelograms have two sets of parallel lines; trapezoids only have once set of parallel lines.

The formula for finding the area of a triangle is...

• b x h

• b + h

• b x h/2

• l x w

What is the area of a trapezoid when b₁ = 4 in, b₂ = 8 in, and h = 7 in?

• 112 in sq

• 84 in sq

• 42 in sq

• 19 in sq

The formula for finding the area of a trapezoid is...

• (b1 + b2) x h/2

• 1/2(b1 + b2) x h

• 1/2h x (b1 + b2)

• All of these are correct
