Answer:
C. 40.5 cm²
Step-by-step explanation:
Use the formula for the area of a trapezoid:
A = (1/2)(b1 +b2)h
The bases are the parallel sides, 4.5 cm and 9 cm. The height is the perpendicular distance between them, 6 cm. Filling in these numbers, we have ...
A = (1/2)(4.5 +9)(6) = 40.5 . . . cm²
Equation can be used to find x is 60/55 + 60+x = 2.75
The time of going to rink is 2.75
We know,
speed = distance/time
⇒ Time = distance / speed
<h3>How to solve?</h3>
(1) Way to rink
Given :
Distance = 60 miles
Speed = 55 miles per hours,
⇒ Time taken by him = Distance / speed = 60/55 hours
(2) Way to home
Given : Distance = 60 miles
Let Speed be x,
⇒ Time taken by him = distance/speed = 60/x hours
Total time taken = 60/55 + 60+x
According to Question, Total time = 2.75 hours,
Thus, 60/55 + 60+x = 2.75 is the required equation.
