Hi so I’m going to answer your problem which is “List three words or phrases used in real life that indicate positive numbers,” so let’s get right into it!
You can it as temperature too, today is 80+ degrees outside!
You can also use an the floors of which an elevator takes you in which direction it takes upwards or downwards like “take the elevator 4 floors up”
You can also use gas as a thing we use in real life, it also indicates numbers
Like gas is __ a gallon cheaper this week
Length is l
width is w
l*w = 30
2l + 2w = 34
You can simplify the second equation to l + w = 17
Factors of 30:
30*1
15*2
10*3
6*5
Try adding each of these factors together, to find out which equals 17
30 + 1 = 31
15 + 2 = 17
10 + 3 = 13
6 + 5 = 11
So the dimensions of the rectangle are 15m * 2m
The area is Base * Height
Area = b * h
b =12 3/4 in
h = 2 1/2 in
Area = 12.75 * 2.5 = 31.875 or 31 7/8 square inches.
