Hello!
We can find the area of the trapezoid using the formula for area of a trapezoid:
FORMULA:
A = [(b + b) * h / 2]
SUBSTITUTE:
A = [(13.5 + 27.5) * 14 / 2]
SOLVE:
A = 41 * 14 / 2
A = 574 / 2
A = 287 cm²
So, the area of the trapezoid is 287 cm².
B there is 4 different third of the pie I’m pretty sure 4/3
2.1%
You might wanna double check though just incase.
From the info
You would use the tan x=5/2
But u would take the inverse of tan or 1/tan
The tan^-1(5/2)
=21.80140
The angle of b would be 21.80
Hope it helps
