Finding the missing length in a figure There is an L-shaped figure shown with sides meeting at right angles. To trace out the figure, we start by going up to form a side of length 13 ft. Then we
go left 4 ft, down 8 ft, left 6 ft, and down 5 ft. From there, we complete the figure by going right to form a side that ends at the starting point. Find the
length of this side. Be sure to include the correct unit in your answer.
