Do you know how to find the area of a square? The area of the shaded region can be found by first finding the area of the larger square and then you subtract the area of the smaller square
so basically area of larger square - area of smaller square what is the area of the larger square? area = side * side the side is (x+8) what is the area?
x^2+16x+64
Good! Now what about the smaller square that has side 7
so x^2+16x+57
no no you have to first find the area of the smaller square with side 7 area = 7 * 7 and then we have to subtract that from the area of the larger square
yeah the area of the smaller square is 49 and I subtracted that and got x^2+16x+57
how did you subtract it to get that? you have x^2 + 16x + 64 - 49 what is 64 - 49 = ?
oh 18 so its x^2+16x+18
I accidentally subtracted 7 my bad
uhhh no 64 - 49 = 15
Oh my gosh I'm stupid I don't know how that happened sorry
is it units, cubic units, or square units

@snowflake0531
Area is always square units
ok thanks
yw~
yes, remember the side length is `units` the area is always going to be `square units` volume will always be `cubic units`
