Question

The area of a parallelogram can be thought of as twice the area of a
triangle. Use this idea to complete this proof of the rule for the area of a parallelogram.
Area = twice triangle area
= 2 x _________
=___________

Answer 1

b = base

h = height

The area of a triangle:

At = 1 / 2 b ∙ h

The area of a parallelogram:

Ap = 2 ∙ At = 2 ∙ 1 / 2 b h

Ap = b ∙ h

Answer:

= 2 x 1 / 2 b h
______________

= b h
