Question

perimeter of rectangle=200
length = 40
find the breadth and area of the rectangle​

Answer 1

Answer:

perimeter of rectangle=2(l+b)

given,

lenght=40

=>200=2(40+b)

=>100=40+b

=>60=b

area of rectangle=l×b

=>40×60

=>2400

Answer 2

2(40+b)=200

40+b=200/2

b=100-40

60cm

so, the breadth=60cn

area of rectangle=40×60

=2400cm^2
