A = 104 ft²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A =
h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₂ are the parallel bases
Here h = 8, b₁ = 10 + 6 = 16, b₂ = 10 , then
A =
× 8 × (16 + 10) = 4 × 26 = 104 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)
