FOREVER CHANGED AREAS TOPIC: AREA/ MEASUREMENT Your class of 22 is lining up from recess to go back into the classroom and must maintain social distancing by remaining 180cm apart. What is the length of your line in cm and m?

Step-by-step explanation:

22 students each maintain distancing of 180 centimeters apart.

1-2-3-4-5-6-7-8-9-10-11-12-13-14-15-16-17-18-19-20-21-22

There are 21 spaces between the students in the line.

21 × 180

= 3780

The length of the line is 3780 centimeters.

To convert cm to m, we divide the value by 100.

= 37.8

The length of the line is 37.8 meters.

We have,

To FinD:

⚠️ Considering the lateral width of each student be negligible and then only considering the gap between them.

.................Similarly,

We have, Length of Gap = 180 cm

➝ Total length of gaps = 180 cm × 21 = 3780 cm

Converting into m,

➝ 100 cm = 1 m

➝ 3780 cm = 3780 / 100 m

➝ 3780 cm = 37.80 m

⚘ Length of line:-

In cm ➝ 3780 cm

In m ➝ 37.8 m

━━━━━━━━━━━━━━━━━━━━

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

is there answer choices?
