Frank needs to find the area enclosed by the figure. The figure is made by attaching semicircles to each side of a 40-m ​-by- 40-m square. Frank says the area is 912.00 m^2. Find the area enclosed by the figure. Use 3.14 for Pi. What error might Frank have​ made?

Sorry guys but as you have a small brain

Prove the following(cot0+cosec0)[tex](cot0 + cosec0) { }^{2} = \frac{1 + cos0}{1 - cos0} [/tex]
