Answer:
The answer to your question is the letter C. 13248 square units
Explanation:
Data
Right triangle Rectangle
short leg = 69 base = x + 100
hypotenuse = 115
Process
1.- Calculate the long leg of the right triangle.
c² = a² + b²
b² = c² - a²
b² = 115² - 69²
b² = 13225 - 4761
b² = 8464
b = 92
2.- Calculate the length of the base of the rectangle
base = 92 + 100
base = 192
3.- calculate the area of the rectangle
Area = 192 x 69
= 13248 square units
