Question

the area of square field is 5184 m square a rectangular field, whose l=2b and perimeter equal to the perimeter of the square field . find the area of the rrectangular field ​

Answer 1

area of square field = 5184

${side}^{2} = 5184 \\ side = 72 \: m$

perimeter of square field= 4 × side

=4×72

=288m

Now ..

perimeter of rectangle field= perimeter of square field

$2(l + b) = 288$

here l=2b

$2(2b + b) = 288 \\ 2 \times 3b = 288 \\ b = \frac{288}{6} \\ b = 48 \: m$

l=2×48

l=96m

Are of rectangle field= l× b

=96×48

$= 4608 \: {m}^{2}$
