Answer:

l=\dfrac{2(S-b)}{P}

Step-by-step explanation:

The surface area formula for pyramids is given by :

S=\dfrac{1}{2}Pl+b ...(1)

We need to arrange the formula for l.

Take b to LHS,

S-b=\dfrac{1}{2}Pl\\\\2(S-b)=Pl\ [\text{cross-multiplying}]\\\\l=\dfrac{2(S-b)}{P}

So, the expression is \dfrac{2(S-b)}{P} for the slant height.
