Keywords:
<em>perimeter, square, base, pyramid, kilometers, side </em>
For this case we must find the perimeter of the base of a square pyramid, whose side of the square measures 160m. In addition, the measure obtained must be converted to kilometers. So, we have by definition the perimeter of a square is the sum of its sides, which is equivalent to , where "l" is the side of the square.
If, then:
Thus, the perimeter of the base of the pyramid is 640m.
On the other hand, by definition:
By making a rule of three we have:
1Km ---------> 1000m
x --------------> 640m
Where "x" represents the perimeter of the base of the pyramid in Km.
Thus, the perimeter of the base of the pyramid is 0.64Km
Answer:
The perimeter in kilometers is 0.64
Answer:
300mm²
Step-by-step explanation:
First we need to break up the shape into separate shapes to make it easier to work out.
<h2>Top :\frac{1}{2} x 15 x 30 = 225
<h2>Bottom : same formula</h2>\frac{1}{2} x 15 x 10=75
<h2>Add them all together</h2>225+75=300mm^2
