Break apart the addends to find the sum 18+21
ololo11 [35]
We break apart the first numer:

10+8

the second:

20+1

and add like this:

18+21=10+8    +  20+1

now, we can mix up the order:

18+21=10+8    +  20+1= 10+20     + 8+1

add the parts:

18+21=10+8    +  20+1= 10+20     + 8+1=30+9=39

The length of the base of a scalene triangle is 22 meters and the height is 14 meters. Find the area of the scalene triangle
Nezavi [6.7K]

Answer:

Area is 154 square meters

Step-by-step explanation:

Well lets think about this

If I take a rectangle and cut it into half diagonally I would get 2 triangles right?

So if I have 2 triangles of the same height and base I can make a rectangle

to find the area of a rectangle I do length times width

So lets take our scalene triangle and multiply our base with its width and then divide by 2

22*14 = 308

308/2 is 154
