Find the Area and Perimeter!

Mathematics
1 answer:
olga_2 [115]3 years ago
7 0

Area of a triangle is 1/2 x base x height.

base = 12

Height = x+6

Area = 1/2 * 12 * x+6

Area = 1/2 * 12x * 72

Area = 6x + 36



Perimeter is the sum of the 3 sides:

x-7 + 12 + 2x+5

3x -2 + 12

3x+10


The last choice is the correct answer.
