Question

PQRS is a rectangle with dimensions 28 m by 20 m. POQ
is a triangle such that O is the point of intersection of the
diagonals. Find the area of the shaded region.​

Answer 1

Answer:

Since AOB is the quarter circle the radius of AOB circle has length (

4

2π(10)

)=5π

Given QO=10

QO=RP=10

Since QO is the radius RP also equals

Perimeter =26

2

26

=13=PO+RO

10+10=20

20−13=7

BR+AP=7

5π+10+7=5π+17
