    let the sides of the triangle be a, b and c

    given length of the sides of the triangle are :-

    a = 8cm

    b = 11cm

    c = ?

    semi-perimeter of the triangle is given = 16cm

    since the sum of all three sides of a triangle is it's perimeter

    => (a + b + c)/2 = 16cm

    => 8 + 11 + c = 32cm

    => 19 + c = 32cm

    => c = 32 - 19

    => c = 13cm

    now we will find the area of the triangle by heron's formula which is √s(s-a)(s-b)(s-c) where s is the semi-perimeter of the triangle.

    semi-perimeter of this triangle = 32/2

    = 16cm

    area of the triangle = √16(16-8)(16-11)(16-13)

    = √(16 × 8 × 5 × 3)

    = √(2 × 2 × 2 × 2 × 2 × 2 × 2 × 5 × 3)

    = 2 × 2 × 2√(2 × 5 × 3)

    = 8√30cm²

    Yogita Ingle 5 years, 10 months ago

    GIVEN :
    x + y = 8
    xy = 15.
    {tex} ( x+y )^2 = x^2 + y^2 + 2xy{/tex}
    {tex}x^2 + y^2 = ( x + y )^2 - 2xy{/tex}
    {tex}= 8^2 - 2×15{/tex}
    = 64 - 30
    {tex}x^2 + y^2 = 34. {/tex}
