Question

Mark has a rectangular piece of land of perimeter 1200 m and length 400 m. If he divides the land among five of his sons such that all the plots have an equal perimeter, what is the perimeter of each plot of land?

Answer 1

Answer:

16000m²

Step-by-step explanation:

Let breadth be x

Now,

perimeter of rectangle=2(l+b)

1200=2(400+x)

1200/2=400+x

600=400+x

x=600-400

=200

Area of rectangle=l×b

=400×200

=80000m²

He has 5 sons and 80000m²

each=80000/5

=16000m²

Answer 2

Answer:

560

Step-by-step explanation:

Perimeter = 2(l+b)

1200 = 2(400+b)

2 shifts to the left -------   1200/2 = 400+b, which is 600 = 400 + b

Therefore width is b = 600-400 (which becomes 200)

Now, divide the length by 5 (number of sons), which becomes 400/5 = 80

Now,  2(80+200)

Therefore, Answer is 560
