Step-by-step explanation:
(A) The radius of the circle is=1.8m
Then diameter will be: 2r=
Circumference of circle= =
Area of the circle=
(B) The area of the rectangular backboard of basketball court = 18900
Width=180cm
Area of rectangle= l{\times}b[/tex]
18900=l{\times}180[/tex]
Perimeter of the seating space=2(l+b)
=
=
Perimeter of the basketball court=2(l+b)
=
=
Now, total perimeter= perimeter of the basketball court+perimeter of the seating space.
Total perimeter=
Area of the seating space=
=
(C) The shape consists of one square and 4 triangles, therefore area of square=
Area of 4 triangles=
=
Area of the shape= Area of the square+ area of the 4 triangles
=

Perimeter of rectangle with length 68 m and breadth=33 m is given by:
Perimeter of the semicircle=
Total perimeter=
Area of rectangle with length=40 m (After converting cm to m) and breadth= 10 m is given by:
Area of rectangle with length 68 m and breadth=33 m is given by:
Area of the semi circle=
Total area=
