Area of the parallelogram is 12 cm²

Step-by-step explanation:

Step 1: The shape is that of a parallelogram. It can also be viewed as a rectangle when the triangle at the right side is placed to the side of the right triangle on the left side. The rectangle is formed with breadth covering 3 squares and length covering 4 squares.

Area of the rectangle = length × breadth

⇒ Area = 4 × 3 = 12 cm²

The solution is $x=-1$ and $x=-0.5$

Step-by-step explanation:

The expression is $2x(x+1.5)=-1$

Multiplying the term $x+1.5$ by $2x$ , we get,

$2x^{2} +3x=-1$

Adding both sides by 1,

$2x^{2} +3x+1=0$

Taking factor, we get,

$\begin{array}{r}{x^{2}+2 x+x+1=0} \\{2 x(x+1)+1(x+1)=0} \\{(2 x+1)(x+1)=0}\end{array}$

Equating the factors to 0,

$\begin{aligned}2 x+1 &=0 \\2 x &=-1 \\x &=-\frac{1}{2}\\x&=-0.5\end{aligned}$ and $\begin{aligned}x+1 &=0 \\x &=-1\end{aligned}$

Thus, the smaller value is $x=-1$

The solution is $x=-1$ and $x=-0.5$
