Calculate the area and perimeter of a right triangle:
Calculate the area and perimeter of a right triangle with a 9" base and sides measuring 12 and 15. Be sure to involve the units in your answer.
Solution:
A = 1/2 bh P = s1 + s2 + b
A = .5(9)(12) P = 9 + 12 + 15
A = .5(108) P = 36 inches
A = 54 square inchesa
