Answer:
No. That's not correct.
Explanation:
Length of the garden: There are 22/2 = 11 lots of 2 inches so that is equivalent to 11 * 3 = 33 ft.
Width of the garden: There are 13/2 = 6.5 lots of 2 inches so that is equivalent to 6.5 * 3 = 19.5 ft.
So the area of the garden is:
33 * 19.5
= 643.5 ft.
