Answer asap plz !
How do I solve the triangles ?

I'm so sorry I only found the area of the first triangle with the measurements 11, 10 and 17

I'll show you how to find the area

Step-by-step explanation:

The formula for a triangle is base x height divided by 1/2

For the first triangle the base is 11 and the height is 10

base(11) x height(10) = 110 then divide 110 by 1/2 = 55

so the area of the first triangle is 55.

Sorry again this is only the area of the first triangle.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
