The graph below shows the design for the front view of a doghouse that Jeremy plans to build. if each square on the graph represents 1 foot, find the perimeter of the design. please use step by step instructions.

D. 28 feet

Step-by-step explanation:

The perimeter of the design is the total distance around it. Since each square on the graph represents 1 foot, then

Base of the design = 8 squares = 8 feet

Length of one side = 5 squares = 5 feet

Length of the other side = 5 squares = 5 feet

To determine the length of each side of the roof, we would apply Pythagoras theorem which is expressed as

Hypotenuse² = opposite side² + adjacent side²

Opposite side = 3 feet

Adjacent side = 4 feet

Hypotenuse² = 4² + 3² = 16 + 9 = 25

Hypotenuse = √25 = 5 feet

Length of both sides of the room is

2 × 5 = 10 feet

Therefore,

Perimeter of the design = 8 + 5 + 5 + 10 = 28 feet
