Answer:
Base = (4√6+1) cm
Height = (4√6-1) cm
Step-by-step explanation:
Let the height be h
Therefore, base = (h+2)
Also, given that,
Area = 48 cm sq.
But, we know that,
Area of triangle = ½ × base × height
Substitute the respective values to get,
=> ½ × (h+2) × h = 48
=> h(h+2) = 48×2
=> h^2 + 2h = 96
=> h^2 + 2h - 96 = 0
=> h = {-2 ± √(2^2 -4(1)(-96))}/2(1)
=> h = (-2±√(4+382))/2
=> h = (-2±√386)/2
=> h = (-2±2√96)/2
=> h = -1±√96
=> h = -1±4√6
But length can't be negative.
Therefore,
=> Height = -1+4√6 cm
And
=> Base = 1+4√6 cm
