Answer:
14 kilometers
Step-by-step explanation:
This is really about calculating perimeter.
So we need the lengths of all the sides of this right triangle.
Notice all the legs are 4 units or 4 kilometers
the hypotenuse is 4*root(2) because this is a 45-45-90 triangle.
so
Perimeter = 4 + 4 + 4
let us add: P = 4 + 4 + 4root(2) = 13.656854 km.
the nearest kilometer is 14 km.
Answer:
a
Step-by-step explanation:
because 8-2 is 6. and 8 times 5 is 30.
Answer:
66
Step-by-step explanation:
So what you need to do is add up each of the faces so 3 times 3 and 3 times 8. Then after you do that you take the 9 and 24 and add em together. Then multiply 33 by 2. I hope this helps :D
- The opposite sides are parallel and congruent. - The diagonals bisect each other.
- There are 4 right angles. - The diagonals are congruent.
- Show that both pairs of opposite sides are congruent.
Answer:
The first side is 11.5cm, the second is 11.5cm×2 = 23cm, the third is 11.5cm × 3 = 34.5cm,
and the fourth side is 11.5cm × 6 = 69cm.
Step-by-step explanation:
A quadrilateral is a 4 sided shape, while perimeter is the addition of all the sides of the quadrilateral. Since the sides of the quadrilateral is not stade, assume the sides of the quadrilateral is x, therefore 1:2:3:6 = x:2x:3x:6x. The total ratio is x+2x+3x+6x=12x, therefore 12x= 138 , x = 11.5cm, Therefore the first side is 11.5cm, the second is 11.5cm×2 = 23cm, the third is 11.5cm × 3 = 34.5cm, and the fourth is 11.5cm × 6 = 69cm.
