A new lawn has a perimeter of 278ft. And a width of 64ft. A bag of grass seed will cover 384ft of ground. How many bags of grass seed are needed to seed the new lawn

13 bags

Step-by-step explanation:

Area of the lawn: A=lw

w = 64 ft

P = 2 (l+w) = 278 ft ⇒

l = 278/2 - 64 = 75 ft A = 64*75 = 4800 ft²

bags of seed required:

4800/384 = 12.5 or 13 if full bags are sold
