Can someone give me the step by step answers on how to do this? i’m not sure how to do it.

First you need to multiply the two sides of the whole rectangle to get the total area
(X+10)(2X+5) = 2x^2 + 25x + 50
Then you need to find the area of the non shaded region
(X+1)(x+1) = x^2 + 2x + 1
Then to find the area of just the shaded region you have to subtract the whole area by the non shaded area
(2x^2 + 25x +50) - (x^2 + 2x + 1)
= x^2 + 23x + 48
I think that’s the answer I’m not sure :)

Idon’t know this and this isn’t middle school work
