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.
