Question

the perimeter of a triangle is 41x. if the length of two sides are 18x and 7x, find the length of the third side in terms of x.

Answer 1

➩ The third side is 16x units.

Explanation:

Given that,

• Perimeter of a ∆ is 41x
• It's two sides are : 18x and 7x

We need to find the third side in terms of x

We know that,

Perimeter of the ∆ = Sum of all sides

Therefore,

We can say that,

➡ 41x = 18x + 7x + third side

➡ 41x = 25x + third side

➡ 41x - 25x = third side

➡ 16x = third side

Hence,

The third side is 16x units.

Answer 2

Answer: 16x

because the perimeter of a triangle is 41x

=> the length of the third side is 41x - 18x - 7x = 16x
