Question

Fifth grade > DD.8 Area of parallelograms and trapezoids OSX What is the area? Write your answer as a fraction or as a whole or mixed number 2 12 / 2 mi 5 mi square miles Submit

Answer 1

Step 1

Identify the figure.

The figure is trapezium

Step 2

List all parameters

`\begin{gathered} \text{Height h = 5}(1)/(2)\text{ = 5.5} \\ a\text{ = 5} \\ b\text{ = 2}(3)/(4)\text{ = 2.75} \end{gathered}`

Step 3

Write the formula for the area of trapezium and substitute values.

`\begin{gathered} \text{Area of a trapezium = }(1)/(2)(\text{ s um of parallel sides) x Height} \\ =\text{ }(1)/(2)\text{ (a + b) x H} \\ =\text{ }(1)/(2)\text{ ( 5 + 2.75) x 5.5} \\ =\text{ 0.5 x 7.75 x 5,5} \\ =\text{ 21}(7)/(16) \end{gathered}`
