Step-by-step explanation:
1. The area of a parallelogram is the product of its base length and height:
A = bh = (2.7 cm)(5.2 cm) = 14.04 cm²
__
2. The area of a triangle is half the product of its base length and height:
A = (1/2)bh = (1/2)(17 cm)(4 cm) = 34 cm²
To find the average speed in miles per hour, you can find the number of miles Khalil traveled per minute and then multiply that by 60 to convert it to hours.
54 miles/45 minutes = 1.2 miles per minute
1.2 x 60 = 72 miles per hour.
Khalil traveled at an average speed of 72 miles per hour.
