Please help me. I need to find the total perimeter of two rectangles

4x+5 and 2x+7
3x and 3x + 14
I’m so confused.
I don’t need the answer. Just tell me where to start
Thanks so much

4x+5 and 2x+7

I assume you mean the length is 4x+5 and the width is 2x+7
if a rectangle then the perimeter is twice the length + twice the width
= 8 x+10 + 4 x + 14
= 12 x + 24
Thank you so much. This helped me so very much
