B. If 200 people were surveyed, men and women, .10+.15/ .25 of those people like reading... so I multiplied 200x.25 to get 50. Meaning 50 people like reading.
C. If we know 130 men were surveyed then we’d subtract that amount from 200 which is the overall amount of people to get the amount of women surveyed which is 70.

The area of the path is 80 square meters.
What is a rectangle?
A rectangle is a 2-D shape with length and width.
The length and width are different.
If the length and width are not different then it is a square.
The area of a rectangle is given as:
Area = Length x width
We have,
To find the area of the path,
We need to subtract the area of the inner rectangle from the area of the outer rectangle.
So,
The outerrectangle has dimensions 14m by 10m (adding 2m to each side of the flower bed), so its area is:
A outer = 14m x 10m = 140 m²
Now,
The innerrectangle has dimensions 10m by 6m (the original dimensions of the flower bed), so its area is.
A inner = 10m x 6m = 60 m²
Now,
The area of the path.
A path = A outer - A inner
= 140 m² - 60 m²
= 80 m²
Thus,
The area of the path is 80 square meters.
