8a.)
we know that area is length time height
and they give us the mesaurements of 2 walls (26 feet and 9 feet)
and the mesaurement of the last wall ( 18 feet and 9 feet)
all we do is multiply and add them together
soooo
26 x 9 = 234
234 x 2 = 468 (since there are 2 walls that are exactly the same)
and finally our last wall
18 x 9 = 162
and now we add together
468 + 162 = 630
so all together the amount of surface area she has to paint iss
630feet ²
i hope this was helpful:)
and don't forget 2
