A=180" cm"

Explanation:


The formula for the area of a triangle is its length, l, multiplied by its width, w:
"where "A="area", l="length", w="width"
A=l*w

To begin, we know the length of our rectangle is 12 cm:
l=12" cm"

We also know the width of our rectangle is 15 cm:
w=15" cm"

Substitute them into the formula for area of a rectangle (A=lw).
A=12*15

Then, calculate our answer.
A=180" cm"

:. The area of the rectangle is 180 cm.
