Answer 1

Answer:

4cm, 6cm and 8cm

Explanation:

The perimeter of a triangle is 18 cm.

Its three sides are x, 1.5x and 2x.

So we have x+1.5x+2x =4.5x = 18 or

x = 18/4.5 = 4

So the sides are 4cm, 6cm and 8cm.

Answer 2

Answer:

The length of each side is 4cm, 6cm, and 8cm.

Explanation:

Given:

Ratio of sides = 1:1.5:2

Perimeter (P) = 18cm

To find:

Length of each side

Formula:

P = l1 + l2 + l3

Solution:

Since the sides are given to be in the ratio 1:1.5:2, let x be the common multiple.

Therefore, the sides are l1 = x, l2 = 1.5x, and l3 = 2x

The perimeter of a triangle is given as the sum of the length of all sides of the triangle. Therefore,

P = l1 + l2 + l3

Substituting the values of l1, l2, l3, and P, we get

P = x + 1.5x + 2x

18 = 4.5x

x = 18/4.5

x = 4cm

l1 = x =4cm

l2 = 1.5x = 1.5×4

l2 = 6cm

l3 = 2x = 2×4

l3 = 8cm

Therefore, the sides of the given triangle measure 4cm, 6cm, and 8cm.
