Which is the area of the rectangle?

The answer to your question is the letter C. 13248 square units

Step-by-step 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
