Pedro is building a playground in the shape of a right triangle. The base of the triangle is 18 yards. The height of the right triangle is 2 1/3 yards. Find the area of the triangular playground.

area of right triangle = ab/2

                     base = 18yards

                    height = 2 1/3 = 7/3yards

area =  (18 * 7/3) /2 = 42 /2 = 21

hope this answer helps you.....

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
