Answer:
72/324 or 2/9
Step-by-step explanation:
1/6 is 54/324 and that plus 18/324 is 72/324
Step-by-step explanation:
A polyhedron include cube ,prism or pyramid while non polyhedron are sphere, cone and cylinder because they have side that aren't polygon. a prism is a polyhedron with two congruent base ,in parallel planes and the lateral sides are rectangle
Area of the base of the model
3*2 = 6 square feet
Since the actual building 120 times bigger than the model, it should be multiplied with 120
6*120 = 720 square feet

Step-by-step explanation:
Answer: length = 14 meters
Width = 10 meters
Step-by-step explanation:
The rectangular tennis court has two equal lengths,L and two equal widths,W
The area of the tennis court is expressed as
Area = Length × width
The area is given as 140 square meters. It means that
L× W = 140
It's length is 6 meters less than twice it's width. It means that
L = 2W - 6
Substituting L = 2W - 6 into LW = 140, it becomes
W(2W - 6) = 140
2W^2 - 6W = 140
2W^2 - 6W - 140 = 0
W^2 - 3W - 70 = 0
W^2 + 7W - 10W - 70 = 0
W( W + 7 ) - 10( W + 7) = 0
( W + 7 )(W - 10) = 0
( W + 7 ) = 0 or W - 10 = 0
W= -7 or W = 10 meters
The value cannot be negative so W = 10
L = 2W - 6 = 2×10 - 6
L = 20 - 6 = 14 meters
