Answer:
Step-by-step explanation:
we know that
The area of the composite figure is equal to the area of a right triangle plus the area of rectangle
see the attached figure to better understand the problem
step 1
Find the area of the right triangle
we know that
The area of triangle is
where
substitute
step 2
Find the area of rectangle
The area of rectangle is equal to
where
substitute
step 3
Find the area of the composite figure
Adds the areas
They have the same slope, but g(x) intercepts the y axis higher.
Answer:38.64
Step-by-step explanation:2.8*5.5*0.5=7.7
7.7*4=30.8
30.8+(2.8*2.8)=38.64
4500 * 0.0725 = 326.25
750 + 326.25 = 1076.25
Hope this helped though I'm not rally sure
