What is the perimeter of this rectangle pls help

24

Step-by-step explanation:

Perimeter of a shape = sum of all lengths of sides

⇒ Perimeter of a rectangle = (2 × width) + (2 × length)

From inspection of the rectangle:

⇒ Perimeter = (2 × 4) + (2 × 8)

                     = 8 + 16

                     = 24

step-by-step explanation:

10.50 + taxes which added up to 11.50

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
