Answer:
2 1/4
Step-by-step explanation:
In an equilateral triangle, all 3 sides are the same length. If one side length is x, the perimeter is x+x+x or 3x which is equal to 6 3/4 as said in the problem. You get the equation 3x=6 3/4. Dividing both sides by 3, you get x=2 1/4.
Answer:
just add 8+8+8 until you get to the number u want/need and the same with 7. Or you can multiply.
8x1=8
7x1=7
8x3=24 (8+8+8=24)
7x3=21 (7+7+7=21)
etc.
Hope it helps!
Answer:
base = 519.62, height = 173.21 m
Step-by-step explanation:
Let the base and height of the triangle be represented by b and h respectively.
Thus,
b = 3h
Area of a triangle =
x base x height
For the given triangle,
area =
x b x 3h
=
bh
Area of the triangle =
bh
To determine the number of hectares,
36 per hectare = 486
hectare = ![\frac{486}{36}](https://tex.z-dn.net/?f=%5Cfrac%7B486%7D%7B36%7D)
= 13.5
numbers of hectares = 13.5
Area of the hectares = number of hectares x 10 000 m²
= 13.5 x 10 000
= 135000
Total area of the hectares = 135 000 m²
So that,
area of the hectares = area of the triangle
area of the triangle =
bh
135 000 =
bh
270000 = 3bh
bh = ![\frac{270000}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B270000%7D%7B3%7D)
= 90000
bh = 90000
But, b = 3h
3h x h = 90000
3
= 90000
= ![\frac{90000}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B90000%7D%7B3%7D)
= 30000
h = ![\sqrt{30000}](https://tex.z-dn.net/?f=%5Csqrt%7B30000%7D)
= 173.2051
h = 173.21 m
So that,
b = 3 x 173.2051
= 519.6153
b = 519.62
Therefore, the base of the triangle is 519.62 m, while the height is 173.21 m.
