Mathematics

Variation can be direct, inverse or joint.

The wet surface area is 60 square feet

The variation is given as:

$\mathbf{F\ \alpha\ As^2}$

Express as an equation

$\mathbf{F\ \ =\ kAs^2}$

Make k the subject.

$\mathbf{k = \frac{F}{As^2}}$

Rewrite as:

$\mathbf{ \frac{F_1}{A_1s_1^2} = \frac{F_2}{A_2s_2^2}}$

Where:

$\mathbf{F_1 = 98,\ A_1 = 50,\ s_1 = 7}$

$\mathbf{F_2 = 135,\ s_2 = 7.5}$

So, we have:

$\mathbf{ \frac{98}{50 \times 7^2} = \frac{135}{A_2 \times 7.5^2}}$

$\mathbf{ \frac{98}{50 \times 49} = \frac{135}{A_2 \times 56.25}}$

$\mathbf{ \frac{2}{50} = \frac{135}{A_2 \times 56.25}}$

$\mathbf{ \frac{1}{25} = \frac{135}{A_2 \times 56.25}}$

Make A2 the subject

$\mathbf{A_2 = \frac{25 \times 135}{56.25}}$

$\mathbf{A_2 = \frac{3375}{56.25}}$

$\mathbf{A_2 = 60}$

Hence, the wet surface area is 60 square feet
