Justin has a paper parallelogram with a
lotted line drawn on it. He will use scissors
o cut along the line, forming a triangle and
pentagon
7 cm
8 cm
3 cm
3 cm
Which equation can be used to find p. the
area of the pentagon?
A p= (7 6 / (3.3)
Bp=(7-6)-(3.3)
cp-417.6.3.3)
Dp = (7 + 6) - (3 + 3)

Answer 1

A

Explanation:

Area of pentagon = Area of parallelogram - area of triangle

= (base * height ) -
`(1)/(2)*b*h`

= (7 * 6) -
`(1)/(2)` * 3 * 3
