Hello!

Answer:


\Large \boxed{\sf P =20+4w}\\\Large \boxed{\sf A =24+12w}

Explanation:

We have the formulas:


\sf P = 2l + 2w


\sf A = l * w

Replace length and width by the values:


\sf P = 2l + 2w = 2*(4+2w)+2*6 = 8+4w+12 = \boxed{\sf 20 + 4w}


\sf A = l * w=(4+2w) * 6 = \boxed{\sf 24 + 12w}
