In a parallelogram the base and height are in the ratio 5:2 if the area of parallelogram is 360 meter square, find its base and height

  • Mathematics - ,

    Area = bh

    b =5/2 h

    Area = 5/2 h h

    360 = 5/2 h^2

    144 = h^2
    12 = h
    base = 30
    check.
    30/12 is a 5/2 ratio of b/h

  • Mathematics - ,

    or
    let the base be 5x and the height be 2x
    (5x)(2x) = 360
    10x^2 = 360
    x^2 = 36
    x = 6

    so the base is 30 and the height is 12

    yes ans ! c0rrect

  • Mathematics - ,

    answer is correct 100%

  • Mathematics - ,

    The easiest way to do it is :
    Let the ratio be x
    Area of a parallelogram= base × height
    360m^2= 5x × 2x
    360 = 10x^2
    360÷10 = x^2
    36= x^2
    6=x
    So, base is 5×6=30m
    Height is 2 × 6= 12
