width = 10 feet → C
let l represent the length then width = l - 8
perimeter = 2(length + width) = 2(l + l - 8)
given perimeter = 56 then
2(2l - 8)= 56
divide both sides by 2
2l - 8 = 
= 28
add 8 to both sides
2l = 28 + 8 = 36
divide both sides by 2
l = 
= 18
thus length = 18 feet and width = 18 - 8 = 10 feet
Um I said
5 = 16
10 = 32
15 = 48
20 = 64
Ok well check it out work out how long it took to hose 1/7 the of the lawn which is 2/5 hours. Times that by 7 to get the whole lawn: 7 x 2/5 = 2.8 hours hope that helps
Answer:
r=C2
Step-by-step explanation:
C=2r is the equation to find circumference
She needs to work backwards in this case, so:
r=C2
r=The circumference she knows x 2 x 3.14(or 3.14159265359)
