Question

Area of a square is 5184m sq. . A rectangular field whose length is twice it's breadth, has its Peri. equal of the sq. . Find the area of rcatangular field

Answer 1

Answer:-

Step-by-step explanation:

Area= 5184 sq.m

let breadth = X cm

length = 2x cm

area of rectangular field= perimeter of rectangular field

so,

l×b=2(l+b)

5184=2(2x+x)(here area of rectangular field is given as 5184sqm)

5184=4x+2x

5184= 6x

X=5184/6

X= 864

length= 2x= 2×864=1728

breadth=X=864

area of rectangular field = l×b

=1728×864

= 149299

I hope this will be correct

Answer 2

Answer:

4608 m sq.

Step-by-step explanation:

Area of square = 5184 m sq.

Side of square = √5184 m = 72 m

perimeter of square = 4 * side = 4 * 72 = 288 m

perimeter of rectangle = perimeter of square

=> 2(l+b) = 288

=> 2(2b+b) = 288

=> 6b = 288 => b = 48 m

So, l = 2b = 48 *2 = 96 m

Area of rectangle = l * b = 48 * 96 = 4608 m sq.
