Length: 9.2 inches, width: 5.5 inches

Length: 8 inches, width: 4 inches
Length: 8 inches, width: 4 inches

Length: 6.5 inches, width: 3.5 inches
Length: 6.5 inches, width: 3.5 inches

Length: 4.5 inches, width: 7 inches

Answer 1

To find the dimensions used on the scale drawing to represent the pool, you need to divide the actual dimensions by the scale factor.

Length on scale drawing = 78 feet / 6 feet x 0.5 inches = 78 / 3 = 26 inches
Width on scale drawing = 42 feet / 6 feet x 0.5 inches = 42 / 3 = 14 inches

Therefore, the correct dimensions for the scale drawing of the pool would be:
Length: 26 inches, Width: 14 inches

So the closest option would be:
Length: 6.5 inches, Width: 3.5 inches

Answer 2

is this correct?

Answer 3

Apologies for the mistake in my previous response. Let's correct the calculations:

Length on scale drawing = 78 / 6 x 0.5 = 6.5 inches
Width on scale drawing = 42 / 6 x 0.5 = 3.5 inches

Therefore, the correct dimensions for the scale drawing of the pool are:
Length: 6.5 inches, Width: 3.5 inches

So, the correct answer is:
Length: 6.5 inches, Width: 3.5 inches

Thank you for catching that mistake!
