Gardens

The garden has the square shape with circumference 124 m. Divide it into two rectangular gardens, one should circumference 10 meters more than the second. What size will have a gardens?

Correct result:

a =  31 m
b =  18 m
c =  31 m
d =  13 m

Solution:


a = 124/4
c = a
2(a+b) = 10+2(c+d)
b+d = a


a = 124/4
c = a
2•(a+b) = 10+2•(c+d)
b+d = a

4a = 124
a-c = 0
2a+2b-2c-2d = 10
a-b-d = 0

a = 31
b = 18
c = 31
d = 13
