Question

The perimeter of a triangle is 49 cm. One side is 7cm longer than
another side and 5cm shorter than the third side. Find the sides.
​

Answer 1

Answer:

let the third side be X

one side is X - 7

another another side X + 5

we know the perimeter of triangle is 49 CM

X + X -7+ X + 5 = 49

3X - 2 = 49

3X = 49 + 2

X = 51 / 3

X = 17

one side is 17 cm

second side is X - 7 = 17 - 17 = 10

third side is X + 5 = 17 + 5 = 22
