If a grassy city park measures 1,116 feet long and 335 feet wide, and there is a rectangular flower garden measuring 107 feet long and 53 feet wide, what area of grass requires cutting?

We assume you want to find the difference in area between the park and the garden. Each rectangle's area is the product of its length and width, so your grass area is

... (1116 ft)(335 ft) - (107 ft)(53 ft) = 373,860 ft² - 5,671 ft² = 368,189 ft²

That's about 8.452 acres.

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
