The width of a rectangle is 6 feet, and the diagonal is 10 feet. What is the area of the rectangle?
Which of the following are measurements of the sides of a right triangle?
A. 3, 4, 5
B. 28, 26, 12
C. 17, 14, 6
D. all of the above
Use the Pythagorean theorem (a^2 + b^2 = c^2), where c = hypotenuse.
6^2 + x^2 = 10^2
Once you find x, multiply by 6 to get area.
Check out your answers for the second post using the same theorem.
