Answer:
23, 24, 25
Step-by-step explanation:
Answer:
28 units^2
Step-by-step explanation:
1. First, let's divide this figure into two shapes: a square and a trapezoid. (Look at the image below explanation for division).
2. Next, we should know the area formulas of the square and trapezoid.
- Square:
, where s = side 
, where a and b = top and bottom and h = height
3. Solving Area of Square and Trapezoid
. Area of square is 16
. Area of trapezoid is 12.- 16 + 12 = 28
Therefore, the area of the figure is 28 units^2.
To find the length of the base using the information given, you will use the formula for finding the area of a parallelogram and solve for the missing base.
A =bh
<u>160.5</u> = <u>7.5b</u>
7.5 7.5
b = 21.4 inches
The length of the base is 21.4 inches.
