Question: The upper surface of the rectangular table shown has length 320 cm and width 125 cm. Find the area of upper surface of the table.



A ) 50000 cm2
B ) 40000 cm
C ) 4000 cm2
D ) 40000 cm2

Steps to derive

1 Area of a rectangle is (l × w), where l is the length and w is the width.

2 = (320 × 125)
 [Replace l with 320 and w with 125.]

3 = 40000
 [Multiply 320 with 125.]

4 So, the area of upper surface of the rectangular table is 40000 cm2.



Hence the right answer is Option D
