A triangle has a perimeter of 280 cm, and its side lengths are a, b and c respectively. If a:b= 2:3, b:c=4:5, find the length of each side of the triangle.​

The length of the sides are 64 cm, 96 cm and 120 cm.

Step-by-step explanation:

Perimeter of a triangle:

The perimeter of a triangle is the sum of it's sides.

A triangle has a perimeter of 280 cm, and its side lengths are a, b and c respectively.

This means that:

a:b= 2:3

This means that:

b:c=4:5

This means that:

At the original equation:

We replace b and c in function of a. So

Multiplying everything by 8

Sides b and c:

Since we have a, we can find sides b and c:

The length of the sides are 64 cm, 96 cm and 120 cm.

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.
