Given: A square ABCD of side = 8cm

           Segment AO and DP = 1 cm each

To Find: Area of AOPD and OBCP

Solution:

  • First we will consider area AOPD.
  1. AO=DP= 1 cm (given)
  2. AD=OP = 8 cm ( OP=BC)
  • ∴ AOPD is a rectangle. Area of rectangle is given by

                           l × b             (1)    

where, l is length and

  and  b is breadth

Substituting values in formula for area we get:

area of AOPD = AO × OP

                        ⇒ 1 cm × 8 cm

                        ⇒ 8 cm^{2}              

  • Now we consider the remaining area OBCP.
  • As in case 1 above OBCP forms a rectangle with the dimensions:
  1. OB=CP = 7 cm    (OB = AB - AO)
  2. OP=BC = 8 cm  

Substituting values in equation (1) we get:

   Area of rectangle OBCP = OB × BC

                                           ⇒ 7 cm × 8 cm

                                           ⇒ 56 cm^{2}

Hence area of AOPD = 8 cm^{2} and area of OBCP = 56 cm^{2}
