Answer:
the answer would be 211
Step-by-step explanation:
you simply add the length and width together to find perimeter. since you have the total perimeter and the length you would instead subtract the two.
292-81= 211
Answer:
68m
Step-by-step explanation:
The perimeter of a rectangle with length and width is given by the following.
P=21+2w
We need to find w when P=292 m and l+78m .
Using these values in the equation above, we'll solve for w.
P=21+2w
292=2(78)+2w
292=156+2w
136=2w
68=w
Subtracting 156 from both sides
Dividing both sides by 2
So the width of the parking lot is 68m
