Question

The extended ratio of the sides of a triangle is 7:8:10. The perimeter of the triangle is 275 cm. How many centimeters is the LONGEST side of the triangle?

Answer 1

Answer:

Longest side = 110 cm

Step-by-step explanation:

The extended ratio of the sides of a triangle is 7:8:10

Let sides are 7x, 8x and 10x.

The perimeter of the triangle is 275 cm.

Perimeter of a triangle = sum of all sides

7x+8x+10x = 275

25x = 275

x = 11

Longest sides of the triangle = 10x

= 10 (11)

= 110 cm

So, the longest side of the triangle is 110 cm.
