Question

18cm and 16cm are the length & breadth of a rectangle.If the length is decreased by 6 cm & breadth is increase by 4 cm.find difference in area.
$please \: solve \: my \: problem.$
​

Answer 1

Answer:

l=18 cm

B = 16 cm

area of a rectangle = l x B

= 18x16= 288

l =12 cm

B = 20

area of a rectangle = l x B

= 12x20 =240

so now difference between the areas = first area - second area

= 288 -240

=48
