$A = 180 cm$ $A=180" cm"$

Explanation:

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

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

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

Substitute them into the formula for area of a rectangle ( $A = l w$ $A=lw$ ).
$A = 12 \cdot 15$ $A=12*15$

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

$:.$ The area of the rectangle is 180 cm.
