Calculate the perimeter of a triangle whose dimensions are 1m 60cm, 1m 80cm and 2m.

★ AnsWer :

➨ 540 cm

★ Step by step Explaination :

Let triangle be ABC,

1m = 100 cm

Step-by-step explanation:

a = 1 m 60 cm = 1.6 m

b = 1 m 80 cm = 1.8 m

c = 2 m

perimeter = a + b + c = 1.6 + 1.8 + 2 = 5.4 m = 5 m 40 cm

step-by-step explanation:

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
