The length of a house is tree time it width the width of the house is f yards if the perimeter of the house is h yards express h in terms of f

h = 3f

Step-by-step explanation:

Perimeter of house = 2(Length + width)

P = 2(L+W)

If the length of a house is tree time it width, then;

L = 3W

L = 3f (since W =f)

Substitute;

P = 2(3f+f)

P = 2(4f)

P = 8f

If the perimeter is h, then;

h = 3f

The expression of h in terms of f is h = 3f

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two
