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

Answer:
<u>25 minutes</u>
Step-by-step explanation:
From the table,
2 laps takes time 10 min.
4 laps takes time 20 min.
6 laps takes time 30 min.
8 laps takes time 40 min.
10 laps takes time 50 min.
So, we can deduce the relation between the number of laps and time
the time over the number of laps at each row = 5
Which mean 1 lap takes 5 minutes
Therefore, to run 5 laps, it takes = 5 * 5 = 25 minutes
