I will mark as brain list please tell me answer of this question in easy way but Step-by-step.
sum of length and breadth of rectangle is 20 cm and difference between lenght and breadth is 4 cm. then what is the area of the rectangle?
rks27:
l=16/2=8
oop I meant b+b+4=20
2b+4=20
2b=20-4=16
b=16/2=8
l=b+4=8+4=12
therefore l=12 and b=8
area of a rectangle is lxb =12*8=96 and that's your answer!
