Question

A rectangle is to be made with perimeter 100 meters and area 525 sq m. what should be the length of its side​

Answer 1

Answer:

perimeter of rectangle= 2(l+b)

100=2(l+b)

50=l+b

Area of rectangle= l×b

525=l×b

525/b=l

thus 50 - 525/b= l

50= 2(525/b)

25=525/b

b= 21

thus l =25

thus

b=breadth=21

l=length=25
