Question

What is the area of this trapezoid?

Answer 1

30 units²

Explanation:

this ones kinda tricky but basically you need to dilate it all by 2 (to make the figure twice as big)

technically, it would be 7.5 units bc but bc of the dilation it'd be 30

Answer 2

`7.5\:\text{square units}`

Explanation:

The area of a trapezoid is given by the average of the bases multiplied by the height.

What we're given:

• Height of 3
• Bases of 1 and 4

The average of the bases 1 and 4 is equal to
`(4+1)/(2)=(5)/(2)=2.5`

Therefore, the area of the trapezoid is
`2.5\cdot 3=\boxed{7.5\:\text{square units}}`
