Pauley and Ishu are designing a triangular banner to hang in their school's gymnasium. They first sketch the design on paper. The triangle has a base
of 10.5 inches and a height of 7.5 inches. If 1 inch on the drawing is
equivalent to 3 feet on the actual banner, what will the area of the banner
be?

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to
