Question

Can anyone help please? With questions 4 please

Answer 1

a. The area of the garden is 11.68
`m^(2)`

b. $192 and then $177

Explanation:

a. 7.5-2.6 = 4.9, so the rectangular part is 4.9 x 1.3 = 6.37

then
`\pi r^(2)` is the area of a circle, but the 2 ends together are 1/2 the circle

so
`\pi *1.3^(2)` = 5.31, The area of the garden is 11.68
`m^(2)`

b. 11.68/.75=15.57, so you have to buy 16 bags (can't buy a partial bag)

16*$12=$192, then 5($33)+$12=$177
