9.5 =10

Answer 2

The closest to the number of bag needed to cover the rectangular garden is 10 bags.

Area of rectangle

area of rectangle = lw

where

• l = length
• w = width

Therefore,

l = 16 1 / 4 ft = 65 / 4 ft

w = 11 3 / 4 ft = 47 / 4 ft

area of rectangle = 65 / 4 × 47 / 4 = 3055 / 16 = 190.9375 ft²

Therefore,

20 ft² = 1 bag

190.9375 ft² = ?

cross multiply

number of bags = 190.9375 / 20 = 9.546875 ≈ 10 bags
