What does the u stand for in these problems? is it the same as r?
Bezzdna [24]

I think "u" stands for units. u^2 means units squared which is like saying ft^2 if you were looking for the area of something with feet dimensions. So in this case, the circle has a diameter of x units (u) and an area of x units^2 (u^2\\). It is not the same as r. "r" is most always going to be used to represent the radius.

PLEASE HELP ASAP!!!!! IM CONFUSED AND GOT IT WRONG

Answer:

Area of the gym floor = 100.8 square meters

Step-by-step explanation:

Area of the gym floor = Area of rectangle A + Area of rectangle B - Area of the overlap

Area of rectangle A = 105 square meters

Area of rectangle B = 8.4 square meters

Area of the overlap = \frac{3}{25}\times (\text{Area of rectangle A})

                                = \frac{3}{25}\times 105

                                = 12.6 square meters

Area of the gym floor = 105 + 8.4 - 12.6

                                    = 100.8 square meters

Therefore, area of the gym floor is 100.8 square meters.
