Question

25. The perimeter of a triangle is 59 centimeters. Side bis 8 centimeters longer than side a.

Side c is 5 centimeters shorter than twice the length of side a. Find the length of each side.

Answer 1

a = 14cm, b = 22cm, c= 23cm

Explanation:

perimeter, p = a+b+c = 59

side b = a +8

side c = 2a - 5

=> p = a + a +8 + 2a -5 = 59

=> 4a = 56

=> a = 14

b = 14 + 8 = 22

c = 2(14) - 5 = 23
