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

nata0808 [166]

Answer:

The length on the blueprint for an actual length of 65 feet is $16\frac{1}{4}\ inches$

Step-by-step explanation:

Given:

Scale of the blueprint is $\frac{1}{4}\ in=1\ foot$

Length of one side of the house is 65 feet.

Now, as per given data;

1 foot in actual = $\frac{1}{4}\ in$ 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 $\frac{1}{4}$ . Therefore,

Length on the blueprint for 65 feet is given as:

$=\frac{1}{4}\times 65\\\\=\frac{65}{4}\\\\=16\frac{1}{4}\ inches$

Therefore, the length on the blueprint for an actual length of 65 feet is $16\frac{1}{4}\ inches$
