Question

3. If each side of a triangle is doubled then find the ratio of the area of the new triangle
thus formed and the given triangle.​

Answer 1

Answer:

let the side of first triangle be X

side of new triangle = 2X

area of 1st triangle= 1/2×base ×height

= 1/2 × (X) × (X)

= X^2/2

Step-by-step explanation:

area of new triangle = 1/2× (2X) × (2x)

= 2X^2

ratio = (2X)^2 / (x)^2/2

= 4:1
