    Answer:

    @ 45000

    Step-by-step explanation:

    let breadth be X and length be 2 X.

    p=2(l+b)

    900=2×3x

    X=150

    2x=300

    so , a= l×b = 150×300

    =45000

    Answer:

    (a) 45000

    Step-by-step explanation:

    let breadth of rectangle be x m.

    then, length= 2x

    perimeter = 2(l+b)

    =2(2x+x)

    =2*3x

    =6x

    but, perimeter of rectangle is given then,

    6x=900

    x=900/6

    =150m

    so, length (x) = 150

    breadth (2x) = 2*150 = 300

    therefore,area of a rectangle = l*b

    =300*150

    =45000 meter square
