Question

on the blue print for a house a rectangular balcony is 1 inch wide and 1.75 inches long . if the actual length of the balcony is 7 feet which of the following is the perimeter of the balcony

Answer 1

The perimeter of the balcony is 22ft.

Answer 2

Answer:

The perimeter of the balcony is 22 feet.

Step-by-step explanation:

On blue print , length of balcony is 1.75 inches

The actual length of balcony = 7 feet.

So, 1.75 inches = 7 feet

1 inch = $\frac{7}{1.75}$

1 inch = 4 feet

Thus the scale is 1 inch = 4 feet.

On the blue print , the width of the balcony is 1 inch .

So, using scale the actual width = 4 feet

Now the formula of perimeter of rectangle = $2(l+w)$

l =length

w = width

So, the perimeter of the balcony =$2(7+4)$

                                                      =$2*11$

                                                      =$22$

Hence the perimeter of the balcony is 22 feet.
