Question

The lengths of the sides of a right triangle are a and b, and the hypotenuse is c. Find the area of the triangle.

a = 5 ft.; c = 13 ft. A = sq. ft.

Answer 1

I think I do right

Answer 2

\[\sqrt{13^2-5^2}=12\]

Answer 3

so now that we know the length of b is 12, to get the area, you multiply the base and the height, then divide by 2, so we get:
\[A = \frac{1}{2}bh = \frac{1}{2}(12)(5) = 30\]
the area is 30 sq ft.

Answer 4

A= (12*5)/2
A= 60/2
A = 30
