Question

The area of rectangular plot is 2400 square meters and it's length one1/2 times to its breadth what is the perimeter

Answer 1

let the length of the rectangular plot be 1/2b

and breadth be b

area of rectangular park=l×b

2400 = 1/2b×b

2400 = 3/2b because it is 1 and half b so 1/2×1

2400×2/3=b

b= 1600m

1/2b=l

so,l= 800

perimeter of rectangular plot 2(l+b)

2(2400)

4800m
