Divide the perimeter by 3 to get 8 then use the equation for the area of a triangle (a= BH1/2) and your answer is 32
Squares : Triangles
3 : 12
Divide both sides by 3.
The simplest ratio is
1 : 4
p=36
because 15 is 3 times 5 so just multiply the perimeter
7(x+2) = 35
Use the distributive property:
7x + 14 = 35
Subtract 14 from each side:
7x = 21
Divide both sides by 7:
x = 21 / 7
X = 3
The answer is C. 3
