An oval track is made by erecting semicircles on each end of a 46 m by 92 m rectangle. Find the length of the track and
the area enclosed by the track.

Step-by-step explanation:

Length of the Track:

Perimeter of the rectangle + Circumference of the two semicircle

Perimeter of the rectangle=

Perimeter of the rectangle:

Circumference of Two Semicircle with same radius:

Total Length of the track is :

Area Covered by the track is :

Area of the two semicircle + Area of the rectangle

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
