Answer:
the area of the shaded area is 160 cm ²
Explanation:
Hey There!
so the first step in solving this problem is to find the area of the whole shape
This is a trapezoid and the formula for area of a trapezoid is
a = base 1 (20)
b = base 2 (40)
h = height (16)
now we plug in the values
so the area of the trapezoid is 480
The next step is to find the area of the triangle
To do so we use this formula
h = height (16)
b = base (20)
now we just plug in the values
The area of the triangle is 160
