Plot

The plot on which Mr. Kalous is to build a house has the shape of a rectangle. On a 1: 500 scale, its dimensions are 7cm and 5.5cm. Find out the dimensions of the plot. Calculate the parcel size.

Correct result:

a =  35 m
b =  27.5 m
S =  0 m²

Solution:

$a=500\cdot 7\mathrm{/}100=35\text{ m}$

$b=500\cdot 5.5\mathrm{/}100={\displaystyle \frac{55}{2}}={\displaystyle \frac{55}{2}}\text{ m}=27.5\text{ m}$

$S=a\cdot b=35\cdot 27.5={\displaystyle \frac{1925}{2}}=962.5=0{\text{m}}^2$
