Question

Help me please. thank you!

Answer 1

The shape above is a trapezium, so we are going to use the formula for the area of a trapezium which is,

`area = ((a + b)/(2) )h`

Plugging in our values,

`area = ( (2 + 8)/(2) ) * 3 = ( (10)/(2) ) * 3 = 5 * 3 = 15 {cm}^(2)`

So the area will be

`15 {cm}^(2)`
