​

Answer 1

Answer:

circle

Step-by-step explanation:

circle have larger area.                                                                                                                         we know that area of circle = pie multiplied by r^2                                                  pie=22\7 , r=7         area=   22/7 ×7² ⇒ 22/7×49⇒154 meter²                                               area of rectangle = length × breadth                                                                                         given , length=7.5,breadth=10                                                                                 area=7.5×10⇒75 m²                                                                                             ∴The area of circle of radius  7m is grater than the area of rectangle of dimensions 7.5 and 10 m by 79                                                                                                                                                                        

Answer 2

Answer:

here we can answer this question by using area of circle and area of rectangle.

Step-by-step explanation:

area of circle= 7/2^2 π = 38.48 m^2

and area of rectangle= 7.5* 10=75 m^2

how much one area is greater than other= 75- 38.48= 36.52 m^2
