Area of Composite Figures

Answers

Answer:

1) 147

2) 87[tex]m^{2}[/tex]  

Step-by-step explanation:

1) Area of triangle = × base length × height

= [tex]\frac{1}{2}[/tex] × 14 × 10

= 70 [tex]m^{2}[/tex]

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

Radius = half of diameter = [tex]\frac{14}{2}[/tex] = 7m

Area of semicircle = [tex]\frac{\pi 7^{2} }{2} = \frac{\pi49 }{2}[/tex]

= 77[tex]m^{2}[/tex] ( Nearest whole number )

Total area = 77 + 70 = 147[tex]m^{2}[/tex]

2) Divide the shape into 2 rectangles

Area of a rectangle = length × width

Rectangle 1 = 7 × ( 3+3+5 )

= 7 × 11 = 77[tex]m^{2}[/tex]

Rectangle 2 = 2 × 5

= 10[tex]m^{2}[/tex]

Total Area = 77 + 10 = 87[tex]m^{2}[/tex]

Please please find the area for this polygon!

Answers

Answer:

508

Step-by-step explanation:

28*16= 448

6*6= 36

4*6= 24

448+36+24= 508

In order to find the area of a polygon, all you have to do is follow the formula: area = 1/2 x perimeter c apothem. To sum it together, perimeter = the sum of the lengths of all the sides. So add 6, 16, 16, 6, 4, 6, 28, and 18! And then you have 100! Then multiply it by 1/2! So your answer should be 50. Please consider brainliest.
