Is it pressure exerted per unit length or pressure force exerted per unit length? Please tell me.

Yes right @Arun Kumar.
Here it is not mentioned that tank is a triangular or rectangular or as square tank.
so the pressure at a particular point is given by p=wh^2/2 and density of water is given by pgh.

Hydraulic force P= rAh'.
Where h' = depth of center of gravity = h/2 in this case.
So P = r (L*h) h/2 = 9.81 * (1.3)^2 /2. ( L cancel out for per meter length).
Where h' = depth of center of gravity = h/2 in this case.
So P = r (L*h) h/2 = 9.81 * (1.3)^2 /2. ( L cancel out for per meter length).

We know pressure exerted per unit length = ωH2/2.
So, the pressure of water per metre length = (9. 81x103x1.32) /2.
= 8.29 KN.
So, the pressure of water per metre length = (9. 81x103x1.32) /2.
= 8.29 KN.

Here, w = &rho * g.

We know that, pressure= £gh ,where £= density.
Now, pressure exerted by the water (force) = pressure* area = £gh* wh/2 (pre dia is triangular =(1/2)*base*h),
So, pressure exerted per unit lenght(pressure/w) = £gh* h/2 = (1000*9.81*1.3*1.3)/2 = 8.29 kN.
Now, pressure exerted by the water (force) = pressure* area = £gh* wh/2 (pre dia is triangular =(1/2)*base*h),
So, pressure exerted per unit lenght(pressure/w) = £gh* h/2 = (1000*9.81*1.3*1.3)/2 = 8.29 kN.
