Step-by-step explanation:

Answer 2

Aim : To find the sides of the triangle

Given,

Perimeter of the triangle = 14 cm

Let the first side of the triangle be 'x'cm

According to the question,

Second side = (x - 5) cm

Third side = (x - 5) + 3 cm

We know that perimeter is the sum of sides.

Therefore,

x + (x - 5) + (x - 5) + 3 = 14

by removing the brackets,

x + x - 5 + x - 5 + 3 = 14

3x - 10 + 3 = 14

3x - 7 = 14

3x = 14 + 7

3x = 21

x = $\frac{21}{3}$

x = 7cm

Therefore, the sides are :

First side = 7cm

Second side = 2 cm

Third side = 5 cm

Hope it helps!

have a great day!
