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.
