QuestionQuestion
Figure out what the perimeter and area of the triangle?Figure out what the perimeter and area of the triangle?
10 in10 in
b=12 in
h=8 in
SolutionSolution
The area of the triangle is 48in2 because 12x8=96 and then follow the formula and you divide it by 2 and you get 48in2. The perimeter is 32in because if you add all the slides up you get 32in.
