The Solution.
The original dimensions of the garden is:
100 ft x 10 ft
When the original dimension is decreased to 2/5 of its original size, we get:
[tex]Length\colon\frac{2}{5}\times100\text{ ft =2}\times20=40\text{ ft}[/tex][tex]\text{Width: }\frac{2}{5}\times10=2\times2=4\text{ ft}[/tex]The new dimensions of the garden was presented in a drawing scale as below:
[tex]\text{Length: 8 inches =40 ft}[/tex]This implies that;
