    Answer:

    30cm²

    Step-by-step explanation:

    length of hypotenuse = h = 13cm

    length of a side = a = 5cm

    let length of the other side = xcm

    now using pythagoras theorem, we get

    x² + 5²  =  13²

    x² + 25 =   169

           x²  =  169 – 25

           x²  =  144

            x   =  12cm

    area of right angled triangle = 1/2 x (ab)

    where a,b are sides making right angle

    area of triangle = 5×12 ÷ 2

    area of triangle = 30cm²

                       Hope it helps you

    Answer:

    30cm²

    Step-by-step explanation:

    a Leg

    5

    cm

    c Hypotenuse

    13

    cm

    Using the formulas

    A=ab

    2

    c=a2+b2

    Solving forA

    A=1

    2ac2﹣a2=1

    2·5·132﹣52=30cm²
