Question

Which of the following is equal to the perimeter of the figure above? (Angles A, B, C, D, E are right angles.)
r + s + a + b
2r + s + (a + b)
2(r + s) - (a + b)
2(r + s) + (a + b)
2(r + s)

I think it is 2(r+s)

Answer 1

yes, u are right.

Answer 2

r + (r -a) + a + b + s + (s -b)
r + r - a + a + b + s + s -b
2r + 2s
2(r+s)
