Say the width is W and the length is L
L=3W (and of course W=W)
Now you use the perimeter formula P=2L+2W
80=2(3W) + 2W)
80=6W+2W
80=8W Divide both sides by 8
W=10
Now that you know the width, substitute it back into L=3W to find the length
L=3(10)
L=30
The dimensions are length: 30 cm and width: 10 cm
Answer:
The answer is 25
Step-by-step explanation:
(5x)^2=25^2
5x times 5x is 25x^2
25^2 divided by 5x is 5x
The two x's become x^2 and the two 5's just multiply to 25
I think the answer is 716.7 not 100% positive
