Answer:


A_2 = 7.5cm^2

Explanation:

The attachment completes the question

Given


Area = 15cm^2

Required

Area of green triangle


The\ area\ of\ a\ parallelogram\ is calculated as


A_1 = b * h

and


A_1 = 15cm^2

Where:


b=base


h = height

Because the triangle shares exact base and height with the parallelogram, the area of a triangle is calculated as


A_2 = (1)/(2) * b * h

Recall that:


A_1 = b * h

So, we have:


A_2 = (1)/(2) *A_1

Substitute
15cm^2 for
A_1


A_2 = (1)/(2) * 15cm^2


A_2 = ( 15cm^2)/(2)


A_2 = 7.5cm^2

The area of the triangle is 7.5cm^2
