Question

How would I solve the area? The base of the triangle is 25 and dotted ling is 10cm.

Answer 1

is the dotted line in the middle of the triangle?
is the triangle equilateral?

Answer 2

Do you agree with this?

Answer 3

(Taking the difference of those triangles (lower left and the entire left) - to find the area of the upper left triangle.)

Answer 4

yeah so i do same thing to other side just double the area

Answer 5

We will see if the x will be a factor in your answer, then you understand that this left WILL impact the area.

Answer 6

and if x goes away (cancels), then information is correct and we didn't need to know this length,.

Answer 7

so this comes out to a specific number?
