Area of garden

If the width of the rectangular garden is decreased by 2 meters and its length is increased by 5 meters, the area of the rectangle will be 0.2 ares larger. If the width and the length of the garden will increase by 3 meters, its original size will increase by 0.9 ares. Find the dimensions of the garden.

Correct result:

a =  12 m
b =  15 m


(a2) (b+5)=ab+0.2 100 (a+3) (b+3)=ab+0.9 100   5a2b=30 a+b=27  5 a2 b=30 a+b=27  5a2b=30 a+b=27  a=12=12 m b=15
b=15=15 m
