Answer:
x=3.3
P = 60
Step-by-step explanation:
The perimeter of the square is
P = 4s
= 4(7x-8.1)
=28x -32.4
The perimeter of the equilateral triangle is
P = 3s
= 3(10x-13)
=30x-39
The perimeters are equal
28x -32.4 = 30x-39
Subtract 28x from each side
28x-28x -32.4 = 30x-28x-39
-32.4 = 2x-39
Add 39 to each side
-32.4 +39 = 2x-39+39
6.6 = 2x
Divide by 2
6.6/2 = 2x/2
3.3 =x
The perimeter is
30x-39 = 30*3.3 -39 = 99-39 = 60
