Question

The perimeter of a triangular banner is 250 inches. if two sides of the banner are each 92.72 in. long, what is the length of the third side?

Answer 1

length of third side = 64.56 in

Explanation:

the perimeter is the sum of the 3 sides of the triangle.

let x be the length of the third side

given perimeter = 250 in and 2 sides are 92.72 in each, then

x + 92.72 + 92.72 = 250 ( simplify left side )

x + 185.44 = 250 ( subtract 185.44 from both sides )

x = 250 - 185.44 = 64.56

then the third side is 64.56 in
