Question

How do I do this? I don’t understand

Answer 1

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}`
