Question

The perimeter of a triangle is 70 in. the longest side is 10 in. longer than the medium side, and the medium side is 3 in. more than the shortest side. Find the length of each side of the triangle.The length of the longest side is?The length of the medium side is?The length of the shortest side is?

Answer 1

summing the lengths of all sides to get the perimeter, we have, 3x+7 = 70,

3x = 63

x= 63/3 =21 in

the length of the longest side is 10 + 21 =31 in

the length of the medium side is 21 in

the length of the shortest side is 21 - 3 =18 in
