a square with a side length of x+6 has the same perimeter as an equilateral triangle with a side length of 4x. what is the area
of the square
1 answer:
First equate the perimeters:
4(x+6) = 3(4x)
Distribute:
4x +24 = 12x
Solve for x:
8x = 24
x = 3
Sub in x=3 into x+6 to find length of side:
3+6 = 9
Find Area of square:
Area = 9*9 = 81
