Step 1
Identify the figure.
The figure is trapezium
Step 2
List all parameters
[tex]\begin{gathered} \text{Height h = 5}\frac{1}{2}\text{ = 5.5} \\ a\text{ = 5} \\ b\text{ = 2}\frac{3}{4}\text{ = 2.75} \end{gathered}[/tex]Step 3
Write the formula for the area of trapezium and substitute values.
[tex]\begin{gathered} \text{Area of a trapezium = }\frac{1}{2}(\text{ s um of parallel sides) x Height} \\ =\text{ }\frac{1}{2}\text{ (a + b) x H} \\ =\text{ }\frac{1}{2}\text{ ( 5 + 2.75) x 5.5} \\ =\text{ 0.5 x 7.75 x 5,5} \\ =\text{ 21}\frac{7}{16} \end{gathered}[/tex]
