Answer 1

b) 36 sq ft.

Explanation:

6 x 4 = 24 (multiply to find the square after splitting it)

12 - 6 = 6 x 4 = 24 / 2 = 12 (you divide by two because it's a triangle)

24 + 12 = 36

hope this helps :)

Answer 2

b.)36

Explanation:

Formula for area of a trapezoid =
`(a+b)/(2) h`

where a and b = bases and h = height

The sign has the following dimensions

Base 1 = 6ft

base 2 = 12ft

height = 4ft

Using these dimensions we plug in the values into the formula

`A=(6+12)/(2) 4\\6+12=18\\(18)/(2) =9\\9*4=36`

Hence the area of Mr. Wash's sign is 36 square feet.
