Hang on something seems off on this. Don’t we just multiply 90 and 12?

I’m assuming this is an area question. Length * Width

it's only length
the weatherstripping goes around the window -- it does not cover it.

No, use the equation oobleck gave you.

Do 90x12 then whatever that result is multiply by 12 again.
90x12=1080 1080x12 = 12960
Answer = 12960
90x12=1080 1080x12 = 12960
Answer = 12960
