Answer:
6 square meters.
Explanation:
The banner is made up of two congruent triangles and two congruent trapezoids.
The banner forms a triangle with base:
[tex]\begin{gathered} 1\frac{3}{4}+1+1+1\frac{3}{4} \\ =5.5\text{meters} \end{gathered}[/tex]
The height of the triangle = 2 meters.
Therefore, the area of the banner:
[tex]\begin{gathered} A=\frac{1}{2}bh \\ =\frac{1}{2}\times5.5\times2 \\ =5.5m^2 \end{gathered}[/tex]
The measure that is the best estimate of the area of the banner is 6 square meters.
