To find the number of squares in the given figure, we need to count the number of squares present. Let's analyze the figure:

The figure consists of five rows and four columns, with each cell forming a small square. To find the total number of squares, we need to count the squares in each row and then add them up.

Starting from the first row, we have 1 square. In the second row, we have 2 squares. In the third row, we have 3 squares. In the fourth row, we have 4 squares. Finally, in the fifth row, we have 5 squares.

Adding up the squares in each row, we get:

1 + 2 + 3 + 4 + 5 = 15

Therefore, there are 15 squares in the figure.

Now, let's move on to the next question regarding the number of fence posts needed for Crystal's vegetable garden.

Crystal's garden is 5 ft wide and 4 ft long. To calculate the number of fence posts she needs, we first need to find the number of corners in the garden. Since there are 4 corners, we know that Crystal needs at least 4 fence posts.

Next, we need to determine how many posts Crystal needs for each foot of the garden. Since the garden is 5 ft wide, she needs 5 - 1 = 4 posts for the width.

Similarly, since the garden is 4 ft long, she needs 4 - 1 = 3 posts for the length.

Adding up the corner posts and the posts for the width and length, we get:

4 (corners) + 4 (width) + 3 (length) = 11

Therefore, Crystal will need a total of 11 fence posts for her garden.
