What is the area of the composite figure if ab ≅ bc ≅ cd ≅ da ≅ dn?

(2π + 28) mm2
(2π + 32) mm2
(2π + 40) mm2
(2π + 48) mm2

Option 3. (2π + 40) mm².

Step-by-step explanation:

Area of the composite figure = area of MKCD + area of ABCD + area of semi circle with AB as diameter.

Then Area A = (DC + MK)/2 × DN + AB² + (1/2)×π×2²

                     = (4 + 8)/2 × 4 + 4² + (1/2)×π×4

                     = 24 + 16 + 2π = (2π + 40) mm²

Therefore option 3. (2π + 40) mm².

step-by-step explanation:

134.6 us dollars

step-by-step explanation:

1 us dollar = 1.33 canadian dollars

so, 150 us dollars = 150 × 1.33 = $199.5.

in canada, the money mitchell spent = 20 canadian dollars.

remaining canadian dollars with him = 199.5 - 20 = 179.5.

after mitchell returned to us, he exchanged the remaining canadian dollars to us dollars.

179.5 canadian dollars = 179.5 × 0.75 = 134.6 us dollars.
