Step-by-step explanation:
Split the shape into two rectangles as shown in the attachment.
Rectangle I
length = 23 ft
Width = 9 ft
Area I = length * width
= 23*9
= 207 ft²
Rectangle II:
length = 13 ft
Width = 26 -9 = 17 ft
Area II = 13 * 17
= 221 ft²
Area of the entire polygon = 207 + 221
= 428 ft²

The solution is
and ![x=-0.5](/tpl/images/0469/3875/bfc2f.png)
Step-by-step explanation:
The expression is![2x(x+1.5)=-1](/tpl/images/0469/3875/84591.png)
Multiplying the term
by
, we get,
Adding both sides by 1,
Taking factor, we get,
Equating the factors to 0,
Thus, the smaller value is![x=-1](/tpl/images/0469/3875/66413.png)
The solution is
and ![x=-0.5](/tpl/images/0469/3875/bfc2f.png)
