Answer:
A.
Two A's: 11.5 × 4 = 46 (since there are 2 A's, double that) 92 m
Two B's: 3.8 × 4 = 15.2 (since there are 2 B's, double that) 30.4 m
Two C's: 11.5 × 3.8 = 43.7 (since there are 2 C's, double that) 87.4 m
B.
Add the three totals.
The total surface area is 209.8 m².
Explanation:
We can model the areas of rectangles B and C using the formula:
A = l × w,
where l is the shape's length, and w is its width.
So, the area of one rectangle B is:
3.8 × 4 = 15.2,
and the area of two of those is:
15.2 × 2 = 30.4
And, the area of one rectangle C is:
11.5 × 3.8 = 43.7.
So, the area of two of those is:
43.7 × 2 = 87.4.
The surface area of the figure is the sum of 2 A's, 2 B's and 2 C's:
92 m + 30.4 m + 87.4 m = 209.8 m
