I'll solve this worksheet problem by calculating the missing base or height for each parallelogram using the formula for the area of a parallelogram: Area = Base × Height.
Let me go through each problem one by one:
Problem 1:
- Area = 72 ft²
- Height = 8 ft
- Base = Area ÷ Height = 72 ÷ 8 = 9 ft
Problem 2:
- Area = 99 in²
- Base = 11 in
- Height = Area ÷ Base = 99 ÷ 11 = 9 in
Problem 3:
- Area = 35 yd²
- Height = 7 yd
- Base = Area ÷ Height = 35 ÷ 7 = 5 yd
Problem 4:
- Area = 180 yd²
- Base = 15 yd
- Height = Area ÷ Base = 180 ÷ 15 = 12 yd
Problem 5:
- Area = 15 ft²
- Height = 3 ft
- Base = Area ÷ Height = 15 ÷ 3 = 5 ft
Problem 6:
- Area = 80 in²
- Base = 10 in
- Height = Area ÷ Base = 80 ÷ 10 = 8 in
Problem 7:
- Area = 84 in²
- Height = 7 in
- Base = Area ÷ Height = 84 ÷ 7 = 12 in
Problem 8:
- Area = 120 yd²
- Base = 12 yd
- Height = Area ÷ Base = 120 ÷ 12 = 10 yd
Problem 9:
- Area = 32 ft²
- Height = 8 ft
- Base = Area ÷ Height = 32 ÷ 8 = 4 ft
The solution to the worksheet is:
1) Base = 9 ft
2) Height = 9 in
3) Base = 5 yd
4) Height = 12 yd
5) Base = 5 ft
6) Height = 8 in
7) Base = 12 in
8) Height = 10 yd
9) Base = 4 ft
