Property

The length of the rectangle-shaped property is 8 meters less than three times of the width. If we increase the width 5% of a length and lendth reduce by 14% of the width it will increase the property perimeter by 13 meters. How much will the property cost if per 1 square meter we will pay € 8.6?

Correct result:

x =  12235908

Solution:


a = 3b - 8
2[(b + 0.05a) + (a-0.14 b)] = 2(a+b)+13
x = 8.6 • 2062 • 690

a = 3•b - 8
2•((b + 0.05•a) + (a-0.14•b)) = 2•(a+b)+13
x = 8.6 • 2062 • 690

a-3b = -8
0.1a-0.28b = 13
x = 12235908

a = 2062
b = 690
