Question

The dimension of model of multistory building are $1m\times 6cm\times 1.25m$. If the model is drawn to a scale $1:60$, find the actual dimensions of the building in meters.
Find ; the floor area of a room of the building, whose area in the model is $250c{m}^2$

Answer 1

$\frac{2^5\times 2^3=2^{5+3}=2^8}{}$

$1m\times 6cm\times 1.25m1:60$

floor area $=?$ are in the modle $250$

$L=60mb=36mw=1.25m\times 60=7500$

Area of floor $=60\frac{(250{)}^2}{10000}$

$=60\times \frac{12500}{10000}=75m^2$
