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.
