Question

how much is the permeter and area of the coloured part?full explanation​

Answer 1

Answer:

radius of the bigger circle=28/2=14m

radius of smaller 2circle=2(7/2)=2m

area of the bigger circle=πr*r

=616 sq m

ar of the smaller 2circle=( π .r .r )2

=77 sq m

ar of rectangle= (5*10) sq m

=50 sq m

ar of the colour part=(area of the bigger circle) - (area of the smaller two circle + area of the the rectangle)= 616-(77+50) sq m=489sq m(ans)
