Answer 1

The formula for the area of a triangle is .



What is the length of the base, b, of a triangle with an area, A, of 110 m2 and a height, h, of 10 m?



2200 m


11 m


22 m


1100 m

Answer 2

i need help on that question to

Answer 3

First divide a from both sides. then subtract b, now I would multiple both sides by -1 to get a nice positive c on the left side! We end up with

\[c=-(\frac{ d-b }{ a})\]

Answer 4

[distribute the a]

ac - ab = d

[add ab to both sides]

ac = d + ab

[divide both sides by a]

c = (d + ab)/a

can also be written as

c = d/a + b

Answer 5

thx

Answer 6

Triangle problem: remember triangle area is \[ \frac{ Base * Height }{ 2 }\]

Let's plug in what we know...

\[Area 110m^2 = \frac{ base* 10m }{ 2 }\]

Solve it and we get 22m!
