Area of Composite Figures
AlekseyPX

Answer:

1) 147

2) 87m^{2}  

Step-by-step explanation:

1) Area of triangle = × base length × height

= \frac{1}{2} × 14 × 10

= 70 m^{2}

Area of a semicircle = \frac{\pi r^{2} }{2} ( r is the radius)

Radius = half of diameter = \frac{14}{2} = 7m

Area of semicircle = \frac{\pi 7^{2} }{2} = \frac{\pi49 }{2}

= 77m^{2} ( Nearest whole number )

Total area = 77 + 70 = 147m^{2}

2) Divide the shape into 2 rectangles

Area of a rectangle = length × width

Rectangle 1 = 7 × ( 3+3+5 )

= 7 × 11 = 77m^{2}

Rectangle 2 = 2 × 5

= 10m^{2}

Total Area = 77 + 10 = 87m^{2}

Ne4ueva [31]

Answer:

118.625

Step-by-step explanation:

Lets clear this up.

M = $65.

6 months = 182.5 days

We may turn 65 into a decimal for a more exact answer.

<h3>65 = 0.65 (changing it to a decimal does not change the value.)</h3>

Now we can do

182.5 x 0.65

= 118.625.

For your homework you could say.

"6 months is 182.5 days, we would need to change 65 into a decimal, which is 0.65 to get a more exact answer. 182.5 x 0.65 = 118.625. Sally will be paid 118.625 in 6 months."
