To find the actual area or perimeter, you need to make the centimeters into meters. But, you have to use the scale. ( 1cm : 320m )
L=13.5
You need to multiply 13.5 and 320 (because that's how much more there is in the other model or the meter's shape)
13.5 * 320 = 4,320.
The actual Length in meters is 4,320.
Do the same with W.
3.3 * 320 = 1,056.
<span>Now you have the real lengths.
</span><span>Area = L * W
</span>So you put in the real measurements.
Area = 4,320 * 1,056
Area = 4,561,920.
Perimeter is the sum of all sides, so Sum up all of the sides' measurements.
Hope this helps <3
Answer:
290 in^2
Step-by-step explanation:
So what you do is you use the formula of the surface area of a rectangle which is SA=2lw+2lh+2hw.
The length=5. The width=5. The height=12.
You put those numbers into the formula.
2(5)(5)+2(5)(12)+2(12)(5)=290 in^2.
Answer:
B and C
Step-by-step explanation:
Like terms are terms with the same constellation of variables. The like terms in this product are (12x) and (-2x). The cells containing those are designated B and C.
20/12 = 1.6 recurring (that is, 1.6666...)
