Answer:
42 ft squared
Step-by-step explanation:
First you must find the sides and heights of each of the shapes, for instance, the trapezoid, the rectangle, and the triangle. After you find the sides and height you would solve for the area using the three area formulas for each shape. Then once you have the three individual areas you would just add each answer together and get 42.
Formulas:
Trapezoid = 1/2(b1 + b2)h
Rectangle = b x h
Triangle = 1/2bh
To find th vertex use the formula -b/2(a) so it's -8/2(1) so it's -4. Plug in the -4 into the original equation -4^2+8(-4)+3
16-32+3
-13
The vertex is (-4,-13)
It's minimum because the first coefficient is positive which means the parabola open up like a giant U and when plotted the vertex is a negative.
The 3 consecutive numbers are 88, 89, and 90. So 90 is the answer.
