Question

5. the longest side of a triangle is 3 times the shortest side and the third side is 2 cm shorter than the longest side. if the perimeter of the triangle is at least 61 cm, find the minimum length of the shortest side.

Answer 1

shortest side: x >= 9. ( >= More or equal)

Explanation:

longest side: 3x

Shortest side: x

Thirt side: 3x - 2

3x + x + 3x - 2 >= 61 cm

7x - 2 => 61

7x => 61+2

x => 63/7

x => 9
