Given the figure of a square pyramid
The area pf the base =area of the square of side 14 in =

the area of the sides = 4 times the area of a triangle of a base of 14 in and a height of 12 in
so, the area of the sides =

So, the surface area of the pyramid =

So, the answer will be A = 532 in^2
12+14= 26%
Convert 26% to a decimal.
26% =.26
250*.26= 65
65 of the marbles were red or blue.
I hope this helps!
