An oval track is made by enclosing semicircles on each end of a 48 m by 96 m rectangle. Find the area enclosed by the track.
-------------
You didn't say which ends have the semicircles.
I'll do it for the 48 m wide ends:
---------
Area of the rectangle = 48*96 sq meters
Area of the 2 semicircles = pi*24^2 sq meters
Add the 2 areas.
==================
Ikelyn's answer makes no sense.
And I quote:
"Area enclosed by the track = 48*96 + pi*(48/2)^2 + pi*(24/2)^2 square meters."

But, it's educational to get different "answers" and then figure out which might be correct.

.

Area enclosed by the track = 48*96 + + square meters. You do the rest.

the length of the oval track is equal to sum of two lengths of the rectangle (each ) and circumference of the circle (you got two semicircles on each end)

assuming that the semicircle is on the end then: radius will be
and the length will be:

=>ans. for the length
the area enclosed by the track will be equal to the area of rectangle plus the area of circle:

...=> ans. for the area
