Question

I need some help with this question.

Answer 1

Answer: 421.1

Explanation:

Area of parallelogram
`= lenth*perpendicular`
`height`
`=12*22=264`

Area of semicircle
`=(1)/(2)\pi r^(2)=(1)/(2) \pi (20)/(2)x^(2) =(1)/(2)\pi *10x^(2) = (1)/(2)\pi *100 = 50\pi =157.079632679`

We know that 20 is the diameter of the semicircle since it is a trapezium

Add together the area of the semicircle and parallelogram to get the total area:
`264+157.079632679=421.079632679=421.1 (1dp)`
