The answer depends on what solving is required: do you need to find the area, perimeter, angles, trigonometric rations?
Let x be the side of the triangle. Thus 4(x-5) is the perimeter of the square.Balance by the perimeter relation,3x = 7+4(x-5)Solve for x,x = 13 inches
To find area given perimeter, rename perimeter to circumference and solve with these formulas: Circumference = 2πr (or 2 * π * r) Area = πr^2 (or π * r * r) With these the area can be found from circumference(or perimeter) as follows: A = π(C / 2π)^2 Now, to find the perimeter given the area; We use A = πr^2 and rearrange then solve: r = √(A / π) So, the circumference would be 2πr = 2π√(A / π)
The answer to this is 4 sides To solve problems like this: Divide the perimeter by 3, 4, 5, 6, 7, etc. Whatever the the lowest number you divide by that has a whole quotient is the answer
