MATHEMATICS ACTIVITIES ON PERIMETER

Even though many students do not like the subject of mathematics, it is essential that students dedicate themselves to the subjects that this subject offers. So, we selected the subject that talks about perimeter for teachers. They can take advantage of the perimeter activity tips and apply in the classroom.

1. Solve the exercises below and place (x) in the correct alternative:

The. Calculate the perimeter of a rectangle 8 cm long by 5 cm wide:

()26 cm

()25 cm

()24 cm

B. If I make 8 turns around a rectangular terrain 16 meters long by 14 meters wide, how many meters will I walk?

( )260 meters

( )480 meters

( )240 meters

c) What is the perimeter of a rectangle 2.50 meters long by 1.20 meters wide?

( )7.30 m

d) Michael purchased a rectangular plot of land 33 m long by 12.50 m wide. What is the perimeter of this plot?

( )90 m

( )91 m

( )92 m

2. Let's remember the subtraction:

a.632 - 573 =

b.3429 – 1202 =

c.954 – 248 =

d.657 - 68 =

e.345 - 67 =

f.347 - 207 =

g.879 - 675=

h.1320 - 456 =

i.546 - 345=

j.54 - 45 =

k.350 - 76 =

1,456 -345 =

m.54 - 32 =

n.67 - 54 =

o.1234 -567 =

p.789 - 123 =

q.767 - 234 =

r.256 – 145 =

s.98 - 43 =

3-

A rectangular football field is 100 meters wide by 70 meters long. Before each practice, players on a team take five and a half laps running around the field. Therefore, determine:

a) How many meters do players run when making a complete turn on the field?

b) How many meters do they cover when making the five and a half turns around the field?

c) If they repeat this run five times a week, how many meters do players run in a week?

4- Consider an isosceles triangle T whose perimeter is 70 cm, decreasing 2 cm at the base of the triangle and increasing 5% on the sides of the same measure, another isosceles triangle is obtained. P of the same perimeter. What are the dimensions of the two triangles?

5- It is known that the perimeter of a rectangle is 60 cm and the length of this rectangle is 22 cm. Set the rectangle's width.

6- Knowing that the perimeter of a regular hexagon is 48.6 cm. What is the measurement of each side of the hexagon?
