Let x be he length of middle piece.
3x = length of longer piece.
x-5 = length of shortest piece.
x + 3x + x-5 = 40
5x - 5 = 40
5x = 45
x = 45/5
x = 9. ( Size of middle piece )
Given that the longer piece is 3 times the size of middle piece,
Longest piece = 3 x 9 = 27.
Size of longest piece = 27 feet
Size of middle piece = 9 feet
Size of smaller piece = 40 - (27+9)
= 40 - 36
= 4 feet.
Thank you.

Step-by-step explanation:
Ashley can help his father and it is a very easy that she can solve for the triangular portion of the roof by using the formula of the area of a triangle which is equivalent to A=1/2*H*B. Ashley needs to measure the length of both base and height of the triangular portion of the roof. Then, she can proceed with the equation.
