Question

Find the value of x, given the perimeter of the

equilateral triangle is 105 m.
P = 3s
3x + 2
3x +2

3x+2. Help me please

Answer 1

11m

Explanation:

perimeter is the distance around the object which is found by adding up all the sides, since the triangle is equilateral all three sides are the same

we know the total of the perimeter is 105m

so if we add up all 3 sides we should get 105

3x + 2 + 3x + 2 + 3x + 2 = 105

9x + 6 = 105

9x = 99

x = 11m
