Question

the area of square field is 5184 metre square a regtangular fieldwhose length is twice its breadthhas its perimetre equal to perimetre of square field find the area of rectangular field​

Answer 1

given,

the area of square is=5184m²

s×s=5184

s²=5184

s=√5184

s=72

according to problem,

l=2x

b=x

we know that,

perimeter of square=perimeter of rectangle

4s=2(l+b)

4×72=2(2x+x)

288=6x

x=288/6

x=48

from problem,

l=2x

=2×48

=96

b=x

=48

therefore length is 96

              breadth is 48

area of rectangle = l × b

                           = 96 × 48

                            =4608 m²

 

Answer 2

here is your answer mate .......

given ar of sq = a^2= 5184

a = √5184= 72m

then perimeter = 4a = 4×72= 288m

let the breadth of rectangle be x then length 2x.

then...

2x+x=288=3x=288

x=288/3=96m

and length = 2×96=192

then area of rectangular field = l×b

192×96 = 18432m^2

ans....
