Answer:
The length is 72
Step-by-step explanation:
length x width = area
9 x length = 648
length = 72
400 to 400-60 which is 340
Does this helps you?
I hope it does but tell me if it doesn't.
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
Answer:
C
Step-by-step explanation:
Use πr²
Im guessing this is a rectangle? If so it would be
16+16+25+25
32+50
82 is the perimeter
