Answer:

Square pizza

Step-by-step explanation:

To obtain which pizza is the best buy:

Cost of square pizza :

AED 80

side length, s = 26cm

Area of square, A = s²

A = 26² = 676 cm²

1 AED of square pizza gives : 676 / 80 = 8.45 cm²

Cost of circular pizza :

AED 80

Radius, r = 28cm

Area of circle, A = πr²

A = 22/7 * 14 * 14 = 22 * 2 * 14 = 616 cm²

1 AED of circular pizza gives : 616 / 80 = 7.7cm²

Hence, square pizza is the better buy ;

8.45cm² > 7.70 cm²
