Answer 2

Step-by-step explanation:

Let base of the triangle be x. We know that,

Area of triangle = 1/2 × base × height

So,

Area of the triangle = 1/2 × x × (x-1)

15 = x( x -1 )/2

15 = x^2 - x / 2

30 = x^2 - x

x^2 - x - 30 = 0

x^2 - 6x + 5x - 30 = 0

x( x- 6 ) + 5( x - 6) = 0

( x + 5) ( x - 6) = 0

Hence, x = 6 units. So,

Base = 6 units

Height = 5 units
