Answer:

(a) F

(b) 30 in

(c) 26 in²

(d) count unit squares, or divide into rectangles and add

Explanation:

Given the coordinates of the points plotted in the attachment, you want to know the perimeter and area of the figure formed.

a) Letter

The figure formed is the block letter F.

b) Perimeter

The sum of the edge lengths is ...

8 + 5 + 2 + 3 + 1 + 2 + 2 + 2 + 3 + 2 = 30 . . . inches

30 inches of tape are required.

c) Area

Considering the line x=4, there is an 8×2 rectangle to its left, a 2×3 and a 2×2 rectangle to its right. The sum of their areas is ...

8×2 +2×3 +2×2 = 2(8 +3 +2) = 2(13) = 26 . . . . square inches

The area of the figure is 26 square inches.

d) How

If you read the above, you see we found the area by dividing the figure into three (3) rectangles. The area of the figure is the sum of their areas.

If you like, you can also count the grid squares. Each square is 1 in². In each column working from the left, their number is ...

8 + 8 + 4 + 4 + 2 = 26 . . . . square inches.

Additional comment

It is easier to get the correct answers if you plot the given coordinates carefully.
