Question

Carrie apartment building ramp has a 2-foot height and a 4-foot base the new building code says the ramp must have a 1:4 height base ratio . How Can Carrie adjust her ramp base to meet the new code ?

Answer 1

The height of building ramp is h = 2 foot.

The base of the building ramp is b = 4 foot.

The code for new bulding is,

$\begin{gathered} \frac{h}{b}=\frac{1}{4} \\ h=\frac{b}{4} \end{gathered}$

Let the new base be x for new building code and height remain same h = 2.

$\begin{gathered} 2=\frac{x}{4} \\ x=8 \end{gathered}$

So Carrie increase the base from 4 foot to 8 foot.

Detemine the adjustment in base.

$\begin{gathered} b^{\prime}=8-4 \\ =4 \end{gathered}$

Thus Carrie increase the base by 4 foot to meet the new code for the building.
