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

Answer:
1260
Step-by-step explanation:
The least common multiple is the smallest positive number which is a multiple of the two. This means 84, 36, and 15 divide into it evenly. To find the multiple:
- We list the prime factors of each number.
- We note how many times each occurs.
- We multiply each factor the greatest number of times it occurs in a number.
84: 2*2*3*7
36: 2*2*3*3
15: 3*5
LCM: 2*2*3*3*5*7= 1260
