Question

The scale for the diagram of the doghouse is 1 in: 3 ft.

Find the length of the actual doghouse.

Answer 1

2.25 feet

Explanation:

Alright so the scale is 1:3

(1 represents the diagram and 3 represents the actual doghouse)

In the diagram the length is 0.75ft

We can use this Information to set up this equation:

`(1)/(3)=(0.75)/(x)`

Simplify: (cross multiply, if confused scroll down, I explained)

x=3(0.75)

x=2.25

Length of actual house is 2.25 feet.

Hope this helps

*************************

Cross multiplying:

It's simply this:

If
`(a)/(b)=(x)/(y)\\`

Then we can say

a(y)=b(x)
