Answer:

The value of
$B (base\ area) = 27m^2$

Explanation:

Let's recall the the formula for volume of a pyramid.

Volume of a Pyramid
....equation

where
$B=Base\ area (m^2)$ and
$H=height\ (m)$

Now we have been given the values of
and
and have to find the value of

Plugging the values of
and
in equation
(1)

$B=(3* V)/(H)= (3 * 81)/(9) = 27\ m^2$

Now we can also check our previous results.

$V = (24* 7)/(3)=8 * 7 =56\ m^3$

So, our final answer is
$27\ m^2$
