The hall

The hall had a rectangular ground plan one dimension 20 m longer than the other. After rebuilding the length of the hall declined by 5 m and the width has increased by 10 m. Floor area increased by 300 m2. What were the original dimensions of the hall?

Correct answer:

a =  0 m
b =  0 m

Step-by-step explanation:


System of equations are non-linear.
The equations have the following integer solutions:
a=20+b
(a-5)*(b+10)=ab+300


Number of solutions found: 1
a1=50, b1=30

Our linear equations calculator calculates it.
