Question

The area of a square field is 5184 m2. A rectangular field, whose length is twice its

breadth, has its perimeter equal to the perimeter of the square field. Find the area
of the rectangular field.​

Answer 1

Answer:

Given: area of square =5184m

2

∴ 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= 6

288

=48m

∴ Length =2×48=96m, Breadth =48m

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

Answer 2

Answer:

Area of square = side^2

5184 m^2 = side ^2

side = 72m

perimeter of square = 72 × 4 = 288m
