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⋅ 7/100=35 ma=500 \cdot \ 7/100=35 \ \text{m}
b=500⋅ 5.5/100=552=27.5 mb=500 \cdot \ 5.5/100=\dfrac{ 55 }{ 2 }=27.5 \ \text{m}
S=a⋅ b=35⋅ 27.5=19252=962.5=0 m2S=a \cdot \ b=35 \cdot \ 27.5=\dfrac{ 1925 }{ 2 }=962.5=0 \ \text{m}^2
