I need help doing this... I’m totally lost

Step-by-step explanation:

Perimeter of a polygon = Sum of the measures of all sides of the polygon

For the given trapezoid,

Perimeter =

By combining similar terms,

Perimeter =

                 =

                 = (2 + 1)a +

                 = 3a +

                 = 3a +

                 = 3a +

                 = 3a +

For rectangle,

Perimeter = 2(Length + Width)

                 = 2(2a + 3b)

Difference between the perimeter of trapezoid and rectangle,

= (3a + ) - 2(2a + 3b)

= (3a - 4a) + ( - 6b)

= -a +

= -a +

= -a +

= -a -

=

6 (3) - 4 + 32

hope this

go on the tube you might find some information there
