Answer 2

Answer:

1.If u find out the area of circular field it is equal to 616m^2.

but sprinkler can spray water up to 240m^2.

so obviously the sprinkler cannot spray water to the entire garden.

2.

In case of square

length of one side will be 11cm

so area of square = side ^2=(11)^2=121cm ^2

in case of rectangle

length =12cm

breath =10cm

area of rectangle = l×b=12×10 =120 cm ^2.

In case of circle

circumference =44cm

therefore length of radius=7cm

area of circle =πr^2=154cm^2

so clearly in case of square the area is maximum..
