Answer 1

Answer:

4608m2

Step-by-step explanation:

Given: area of square  =5184m2

∴ Side of square  =5184=72m

The perimeter of square  =4×72=288m

Let breadth of rectangle =xm

∴ Length of rectangle =2xm

Now, perimeter of rectangle= Perimeter of a square

⇒2(l+b)=288m

⇒2(2x+x)=288

⇒x=6288=48m

∴  Length  =2×48=96m, Breadth =48m

Therefore area of rectangle  =l×b=96×48=4608m2
