Problem 1 :
Each side of a regular polygon is 5.2 m and its perimeter is 36.4 m. Find the number of sides of the polygon.
Solution :
Let x be the number of sides of a regular polygon.
Perimeter of polygon = 36.4
Length of one side of polygon = 5.2 m
5.2x = 36.4
x = 36.4/5.2
x = 7
So, the number of sides of a polygon is 7.
Problem 2 :
Trisha took 3.25 minutes to complete the race and Rachel took 3.207 minutes to complete the race. Who won the race?
Solution :
Time taken by Trisha = 3.25 minutes
Time taken by Rachel = 3.207 minutes
By comparing hundredth places, 0 < 5.
Rachel is taking less time, so he will win the race.
Problem 3 :
The annual rainfall received by Albany is 278.2 cm and that by Rochester is 281.8 cm. Who received less rainfall ?
Solution :
Rain fall in Albany = 278.2 cm
Rain fall in Rochester = 281.8 cm
278 is less than 281.
So, Albany has received less rain fall.
Problem 4 :
Sharon’s height is 145.62 cm. She stands on a tool of height 10.50 cm. What is the combined height now ?
Solution :
Height of Sharon = 145.62 cm
Height of the tool = 10.50 cm
Combined height = 145.62 + 10.50
= 156.12
Problem 5 :
The milkman delivers 5.02 liter of milk to a house in the morning and 2.120 liter in the evening. What is the total quantity of milk delivered by the milkman ?
Solution :
Quantity of milk delivered in the morning = 5.02 liter
Quantity of milk delivered in the evening = 2.120 liter
Total quantity of milk delivered = 5.02 + 2.120
= 7.14 liters
Problem 6 :
Rebecca ‘s kite is flying at a height of 17.2 m and Shelly’s at a height of 21.5 m from the ground. Whose kite is flying high and by how much?
Solution :
Height of Rebecca ‘s kite = 17.2 m
Height of Shelly's kite = 21.5 m
21 is greater than 17. So, Shelly's kite is flying high.
Difference = 21.5 - 17.2
= 4.3 m
So, Shelly's kite is flying 4.3 m more than Rebecca's kite.
Problem 7 :
A car travels 367.80 km in 6 hours. How much distance will it travel in 1 hour?
Solution :
Distance covered by the car = 367.80
Time taken = 6 hours
Distance covered in 1 hour = 367.80/6
= 61.3 km
Problem 8 :
Ron jogged 2.2 km, Mike jogged 3.7 times more distance than Ron. Find the distance covered by Mike.
Solution :
Distance covered by Ron = 2.2 km
Distance covered by Mike = 3.7(2.2)
= 8.14 km
So, distance covered by Mike is 8.14 km.
