Question

pls answer ques no. 7..... fast

Answer 1

area of square field=5184

in rectangular field
lenght=2xbreath

perimeter of square field=perimeter of rectangular field

side of square field= under root area
side of square field= under root 5184
side of square field= 72
perimeter of square field=4xside
perimeter of square field=4x72
perimeter of square field=288
thus perimeter of rectangular field=288

let breath of rectangular field be a
therefore lenght of rectangular field=2a
perimeter of rectangular field=2(2a)+2(a)
peri of rectangular field=6a
288=6a
288/6=a
48=a
breath=48
lenght=2xbreath
therefore lenght=2x48=96

area of rectangular field=lenght x breath
therefore area of rectangular field= 96x48=4608

thus area of rectangular field is 4608 metre square
