In this problem, the shape of the sail is equilateral triangle. You are given that the measurement of each side is x – 10 units. The perimeter is 63 units. You have to formulate an equation to find the value of x. The formula of the perimeter is to get the sum of the measurements of the three sides of the triangle.

x – 10 + x – 10 + x – 10 = 63

3x – 30 = 63

3x = 63 + 30

3x = 93

x = 31

Therefore, the value of x is 31 and the measurement of each sides is 21 units.
