Answer:
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
Given coordinates (0,0) and (34,-78).
Distance = 2(42.544) ≈ 85.09.
Therefore, distance from the origin (0,0) to the point (34,-78) is 85.09 units.
