Answer is 744.82 sq.cm

Answer 2

Answer:

745.5

Step-by-step explanation:

Area of a big circle= πr²

=22/7×(16)²

=804.57142857

Area of a small circle=2×πr²

=2×22/7×(3)²

=56.57142857

Area of rectangular=l×b

=2.5×1

=2.5

Now the addition of square and two small circles,

56.57142857

+02.5000000

=59.07142857

Now remove 59.97142857 from 804.57142857,

we will get 745.5
