Try drawing a diagonal bisecting the figure from point P to S. Do u see the shaded triangles formed with their corresponding right angles heights?

I'd like to share with you a simple trick. Always ask yourself why they give some values and not others. The values they give are usually the clues to unlock the puzzle. Have fun solving. 😉
to find circumference = DXP and includes the radius as well can you find the answer now ?

i mean after you do D X P you have to + the radius

its Quadrant so my bad it would be D x P x 1/4=circumference than + radius

First u need to find the circumference, so C= pi x Diameter x 1/4( cos it's a quadrant) = pi x 28 x 1/4
= 7pi
So, perimeter is 7pi + 14 + 14
= 7pi + 28
Hope u get it
