Find the area of the shaded portion pls ​

91

Step-by-step explanation:

To do this you have to find the area of the total square using A=bh

So, A= (10)(10)

A=100

then find the area of the unshaded square using the same formula

A=(3)(3)

A=9

Then, subtract 100-9=91

So, your answer for the shaded square is 91

I hope this helps :) (if it does, brainliest??)
