Mr. foote placed a cement walk along the side of his house. the walk if 18 inches wide and 32 feet long. what was the cost of the walk at $2.10 a square foot

we know that

1 ft> is equal to 12 in

step 1

find the area of the walk

18 in wide> convert to ft

18/12=1.5 ft

area=1.5*32> 48 ft²

step 2

find the cost at $2.10 a square foot

multiply 48 ft² by $2.10

48*2.1=$100.80

therefore

the answer is

$100.80

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
