The area of the sports field is 10150 square meters and the length of one lap of the track is 400 meters.
<h3>What is the area of the rectangle?</h3>It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
Area of the sports field = area of the rectangle + area of the two semicircle
Area of the sports field = 90×70 + π(70/2)²
= 6300 + (22/7)1225
= 6300 + 3850
= 10150 square meters
Length of the track = perimeter of the rectangle + circumference of the
two-semi circle
= 90 + 90 + 2π(70/2)
= 180 + 70(22/7)
= 180 + 220
= 400 meters
Thus, the area of the sports field is 10150 square meters and the length of one lap of the track is 400 meters.

Answer:
Step-by-step explanation:
In probability, "OR" means "+" and "AND" means "*".
The total amount of people is:
32 + 54 + 78 + 112 + 96 = 372
Number of diabetic patients are 54
Number of eye patients are 112
Since we want "OR", we will add the two probabilities:
P(diabetic or eye problem) = 54/372 + 112/372 = 83/186
