Question

The perimeter of a triangle is 6868 cm. the longest side is 44 cm less than the sum of the other two sides. twice the shortest side is 88 cm less than the longest side. find the length of each side of the triangle.

Answer 1

First, substitute the value of c from eq 2 into eq 1:
a + b + c = 59
a + b + (a + b - 7) = 59
2*a + 2*b - 7 = 59
Add 7 to both sides:
2a + 2b - 7 + 7 = 59 + 7
4. 2a + 2b = 66
