You can
put this solution on YOUR website!The lateral area of a regular pyramid of slant height L, base side length a, and number of
sides n is given by the formula:
.
Slant Area =

.
The problem gives you that the given slant height is 25 cm, the base side length is 14 cm
and I presume that the number of sides is 4.
.
Substituting these values results in:
.
Slant Area =

.
which multiplies out to 700 sq cm. That's the answer.

Hope this helps.
