Answer:
Given,
Side of square pizza =40cm
Diameter of circular pizza =30cm
⇒Radius (r)=15cm
Area of square pizza =side
=30×30 =900cm^2
Area of circular pizza =πr^2= (22/7)×15×15
=707.14 cm^2
Hence,
Amount in Rs. 1 square pizza = 900/100 = 9 cm^2
Amount in Rs. 1 circular pizza = 707.14/150 = 4.71 cm^2
Therefore, the best deal is Square pizza, because we are getting more amount in square pizza than in circular pizza for same price.
