  1. Answer:

    area ⇒30 cm

    2

    =

    2

    1

    (2x−1)(4x)

    60=(4x)(2x−1)

    15=x(2x−1)

    2x

    2

    −x−15=0

    2x

    2

    −6x+5x−15=0

    2x(x−3)+5(x−3)=0

    ⇒x=3,x=

    2

    −5

    since x cannot be negative

    x=3

    ∴AB=(2x−1)=5 cm

    AC=4x=12 cm

    BC=

    AB

    2

    +AC

    2

    =

    25+144

    +

    169

    =13cm.

    ∴ the sides are 5 cm, 12 cm and 13 cm
