Question

9. A blueprint of a house plan uses a scale in

which – inch equals 1 foot. If the length
of one side of the house is 65 feet, how
many inches will the length be on the
blueprint?

Answer 1

The length on the blueprint for an actual length of 65 feet is
`16(1)/(4)\ inches`

Explanation:

Given:

Scale of the blueprint is
`(1)/(4)\ in=1\ foot`

Length of one side of the house is 65 feet.

Now, as per given data;

1 foot in actual =
`(1)/(4)\ in` on the blueprint.

Therefore, using unitary method, we can find find the length on the blueprint for an actual length of 65 feet by multiplying 65 and
`(1)/(4)`. Therefore,

Length on the blueprint for 65 feet is given as:

`=(1)/(4)* 65\\\\=(65)/(4)\\\\=16(1)/(4)\ inches`

Therefore, the length on the blueprint for an actual length of 65 feet is
`16(1)/(4)\ inches`
