Question

let traingle be a area of a triangle find the area of whose each side is twice the side of the given triangle
​

Answer 1

Answer:

4a

Step-by-step explanation:

Let the sides be x, y, z.

Now new sides = 2x, 2y, 2z.

We see, x/2x = y/2y = z/2z = 1/2

Therefore the triangles are similar.

We know that the ratio of areas of two similar triangle is equal to the ratio of the squares of their sides.

So, a/Area of new triangle = x^2/4x^2 = 1/4

So, Area of new triangle = 4a
