Question

the area of a square field is5184m. 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

area of square field=5184
(side) ²=5184
side=√5184
side=72m
perimeter of square field=4*side
=4*72
= 288m
let the breadth of rectangular field be x m
length=2x
A. T. Q
perimeter of square field= perimeter of rectangular field
288=2(2x+x)
288/2=3x
144=3x
x=48m
breadth of rectangular field=x=48m
length of rectangular field=2x=2*48=96m
area of rectangular field=l*b
=48*96
=4608m²
