Question

The height of a right angled triangle is 5 cm less than twice it's base .If area of triangle is 114cm2 Then find length of Base of triangle

Answer 1

Hello friend here is your answer!

Let the height of the triangle be "h" cm

Let the base of the triangle be "b" cm

According to the question:-

h = ( 2 x b ) + 5

  => 2b+5

Area of a right angles triangle = 1/2 x base x height

        114$cm^{2}$           => 1/2 x b x 2b+5

Therefore base = 114 - 5

                          = 109 cm
