What is the area of the composite figure if AB ≅ BC ≅ CD ≅ DA ≅ DN?
bekas [8.4K]

Answer:

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.

Decompose 8/12 in two ways with: <br> x/2 + x/2 = 8/12
LUCKY_DIMON [66]
\frac{x}{2} + \frac{x}{2} = \frac{8}{12} \\\frac{2x}{2} = \frac{2}{3} \\x = \frac{2}{3}
or
\frac{x}{2} + \frac{x}{2} = \frac{8}{12} \\\frac{x}{2} + \frac{x}{2} = \frac{2}{3} \\\frac{\frac{2}{3}}{2} + \frac{\frac{2}{3}}{2} = \frac{2}{3} \\\frac{1}{3} + \frac{1}{3} = \frac{2}{3} \\\frac{2}{3} = \frac{2}{3}
