C it’s 366 cm that’s how you would know the rectangular board
Step-by-step explanation:
take the length of side ab and multiply it by side cd
The mean is the average, which is the sum of all the numbers divided by the total numbers there are. I will add them up for you, and then work from there.
184 + 192 + 164 + 200 = 740.
There is 740cm total, but now we need to divide by how many students we have. We have 4 students total.
740/4 = 185.
Your average (mean) height of the students is 185cm.
I hope this helps!
D a rectangle because it has four sides easy for abcd
15/100 × 215 = 3225/100
= 32.25
