What is the set solution for 4x-3> 5 or -2x-7> 1

the area of the shaded area is 160 cm ²

Step-by-step 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
