1. Adele let out 18 m 46 cm of string to fly her kite. She then let out 13 m 78 cm more
before reeling back in 790 cm. How long was her string after reeling it in?
a. Design an equation with letters to stand for any missing information.
b. Create a visual model and solve the problem
2. A new state park has been established and they need to cover the land with tree
seeds. The northern section has an area of 8 square kilometers, the central section
has an area of 3,128 square meters, and the southern section has an area that is 625
square decameters smaller than the northern section. To fill one square meter with tree
seeds costs $8. What will the cost be to fill the park with new trees?

Practice Set B Answer Key
1. Adele let out 18 m 46 cm of string to fly her kite. She then let out 13 m 78 cm more
before reeling back in 790 cm. How long was her string after reeling it in?
a. Design an equation with letters to stand for any missing information.
L = length of Adele’s string
1,846 cm + 1,378 cm - 790 cm = L;
2,434 = L
b. Create a visual model and solve the problem
2. A new state park has been established and they need to cover the land with tree
seeds. The northern section has an area of 8 square kilometers, the central section
has an area of 3,128 square meters, and the southern section has an area that is 625
square decameters smaller than the northern section. To fill one square meter with tree
seeds costs $8. What will the cost be to fill the park with new trees?
8,000 m + 3,128 + 8,000 - 6,250 = 12,878
12,878 x $8 = $103,024
