Answer:
length = 78 m , width = 27 m
Step-by-step explanation:
let w represent width then length l = 3w - 3
the perimeter (P) is calculated as
P = 2l + 2w = 210 , substitute values
2(3w - 3) + 2w = 210 ← distribute parenthesis and simplify left side
6w - 6 + 2w = 210
8w - 6 = 210 ( add 6 to both sides )
8w = 216 ( divide both sides by 8 )
w = 27 and l = 3(27) - 3 = 81 - 3 = 78
Then length = 78 m and width = 27 m
7 times 2=14
14 times 2=24
24 times 1=24
Answer:
20..... 1/10
Step-by-step explanation:4x5 equals twenty
2/20 divided by 2 is 1/10
4 and 8 twelves - 1 and 11 twelves
4 8/12 - 1 11/12
= 2 3/12
Answer : 2 3/12 simplified to 2 1/4
Check answer:
2 9/12 + 1 11/12 = 4 8/12
