Answer:The length of the first side is 7.5 feet.

The length of the second side is 22.5 feet.

The length of the third side is 18 feet.

Explanation:

The formula for determining the perimeter of a triangle is expressed as

a + b + c

Where a,b and c are the length of each sides of the triangle.

A triangle has a perimeter of 48 feet. It means that

a + b + c = 48 - - - - - - - - - - - - - - 1

The second side is 15 feet longer than the first side. It means that

b = a + 15

The third side is 3 feet longer than twice the first side. It means that

c = 2a + 3

Substituting b = a + 15 and c = 2a + 3 into equation 1, it becomes

a + a + 15 + 2a + 3 = 48

4a + 18 = 48

4a = 48 - 18 = 30

a = 30/4 = 7.5

b = a + 15 = 15 + 7.5

b = 22.5

c = 2a + 3 = 2 × 7.5 + 3

c = 18
