Heya......!!
From the figure which have provided .
Let AB = x ,, BC = 2-x
from ∆ABD
H = ( 1.3 ) ² - x ²
H = 1.69-x ² ....................... i
from ∆ BCD
H = 2 ² - ( 2-x ) ²
H = 4x - x ² ...................... ii
from eq. i and ii
1.69 - x ² = 4x - x ²
x =>> 1.45
From eq. i
H= 1.69 - 1.45 ²
➡H = 1.23 meter ( m ) .
