Length (L): 2w + 6
width (w): w
Perimeter (P) = 2L + 2w
66 = 2(2w + 6) + 2(w)
66 = 4w + 12 + 2w
66 = 6w + 12
48 = 6w
8 = w
Length (L): 2w + 6 = 2(8) + 6 = 16 + 6 = 22
Answer: width = 8 ft, length = 22 ft
440000 because the decimal is positive you move the decimal place five places to the right.
Answer:
-54
Step-by-step explanation:
it is -54 because you must subtract 19 every time.
Break up the shape into two so you have:
A rectangular prism dimensions 4x2x5
A rectangular prism dimensions 5x3x14
Now you can find the volume of each:
4·3·5 = 60
5·3·14 = 210
Add the two volumes up to get the volume of the composite figure:
210 + 60 = 270
