Alchen [17]

Answer:

The slant height of the pyramid is $9\ in$

Step-by-step explanation:

we know that

The lateral area of the square base pyramid is equal to

$LA=4(\frac{1}{2}(b)(L))$

where

b is the length side of the base

L is the slant height of the pyramid

we have

$LA=270\ in^{2}$

$b=15\ in$

substitute the values and solve for L

$270=4(\frac{1}{2}(15)(L))$

$270=30(L)$

$L=270/30=9\ in$
