Step-by-step explanation:
I think it eould be 17 feet. 5 plus 8 plus 4 is 17.
Because when you add them all up that's what the answers are
Since 90 degree is 1/4 of a circle, the area will be 1/4 th area of the full circle.
The radius is given by, r = 8 ft, therefore, the area of the full circle is,

Therefore, the area of the sector is,

it's rational number because it's in the form of p/q
