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.

Result

a =  12 m
b =  15 m
