Area of Composite Figures

1) 147

2) 87  

Step-by-step explanation:

1) Area of triangle = × base length × height

= × 14 × 10

= 70

Area of a semicircle = ( r is the radius)

Radius = half of diameter = = 7m

Area of semicircle =

= 77 ( Nearest whole number )

Total area = 77 + 70 = 147

2) Divide the shape into 2 rectangles

Area of a rectangle = length × width

Rectangle 1 = 7 × ( 3+3+5 )

= 7 × 11 = 77

Rectangle 2 = 2 × 5

= 10

Total Area = 77 + 10 = 87

the correct answer is b) histograms can be used to exhibit the shape of distributions. this is because histograms count the frequency of each possible answer, so one is able to see which results are more common and which are less common.
