Question

Please help me I don’t quite get it..

Answer 1

Answer is B

Area = area of rectangle + area of that small areched shape

Area is little bit more than (60*40)=2400

Which is covered by 2 bags (2400/1200) =2

Cost of 2 bags is 2.5*2=5

So..you have to choose what is more than 5 with little amout..which is 5.51

Answer 2

Explanation:

the lawn above is 40 x 60= 2400 ft^2

one bag of seed that costs $2.50 and it covers 1200 ft^2

if your lawn is 2400 ft^2 you divide it by the 1200 ft^2

2400 ft^2 / 1200 ft^2 = 2

so if 1 bag covers 1200 ft^2 then you will need 2 bags to cover 2400 ft^2.

at $2.50 a bag your answer will be, B.
