Classify the triangle shown below. check all that apply.

The first classification we can say about this triangle is that it is obtuse (since it has an angle greater than 90 degrees). But, it's also isosceles. In an isosceles triangle, the base angles (two angles) are equal. So, since two angles are equal here, that means that this triangle is also isosceles.

the perimeter is increased by a factor of 2

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
