Question

If a shark's tooth is shaped like a triangle the height of the is 3cm longer than the base .The area is 14cm2 how do i find the height and base?

Answer 1

what's the formula for the area of a triangle?

Answer 2

14cm squared

Answer 3

no, what is the formula to figure out a triangle's area from its base and height?

Answer 4

this was a word question so i didn't see a formula

Answer 5

no, i'm asking you if you know the formula to find a triangle's area from its base and height!

Answer 6

you know, like area of a square is side x side? what's area of a triangle?

Answer 7

no it's to find the sharks teeth length that are shaped like a triangle

Answer 8

I KNOW! WHAT IS THE FORMULA FOR THE AREA OF A TRIANGLE?!

Answer 9

I'm trying to helpfully lead you to the solution, but you're not really cooperating.

Answer 10

14cm2*14cm2=

Answer 11

OK, I'll give it to you. The area of a triangle is 1/2 base x height.

Answer 12

and you know height = base + 3, and area is 14.

Answer 13

so is it 14*3=

Answer 14

no. Area = 1/2 base * height. So it's 14 = 1/2(base)(base + 3)

Answer 15

because 14 is the area, base is what we're solving for, and height is base + 3.

Answer 16

1/2*14cm2*3=

Answer 17

no. you multiply out the earlier equation to get 28 = base2 + 3base. And then base2 + 3base - 28 = 0. Then you factor into (base + 7)(base - 4) = 0.

Answer 18

okay I think I got it now .

Answer 19

OK, good. :-)
