Explanation:
The formula for the area of a trapezium is :
![(a+b)/(2) *height](https://img.qammunity.org/2021/formulas/mathematics/college/iel3x02177r8wvv2irng8xqvudd9gmdn69.png)
A is the top line
B is the bottom line
To work this out you would first add 6 to 10, which is 16. Then you would divide 16 by 2, which is 8. Then you would multiply 8 by 8, which is 64

1) Add 6 to 10.
![6+10=16](https://img.qammunity.org/2021/formulas/mathematics/college/db0yurvyx8s7mmma6oa280x3okh6b3go2b.png)
2) Divide 16 by 2.
![16/2=8](https://img.qammunity.org/2021/formulas/mathematics/college/olli1gox1p1imtw1xs3vfz30sja0wnp8ig.png)
3) Multiply 8 by 8.
