Perimeter of the triangle is 30.75 inches.
Step-by-step explanation:
- Step 1: Given sides of the triangle = 11.25 in, 9.25 in, 10.25 in
- Step 2: Formula for perimeter of triangle = length of sides of the triangle
- Step 3: Substitute in the formula
Perimeter = 11.25 + 9.25 + 10.25
= 30.75 inches

Answer:
Step-by-step explanation:
Area of the good part= area of whole roof - area of bad part
Since the roof is a square roof, the area will be calculated using the formulae for area of a square
Area of a square =length²
Area of good part =(x+12)²-x²
A= {(x+12)(x+12)} - x²
A = (x²+12x+12x+144) -x²
Open the bracket and rearrange the equation
A= x²-x²+24x+144
A=(24x+144) ft
