Question

Each side of a triangle is doubled find the ratio of the area of two triangle the given triangle and triangle obtained on doubling the side also find the percentage increasing in the area of new triangle

Answer 1

Answer:-

let,

side of traingle (1) = x

base of triangle (1) = y

area of traingle (1) = xy/2

now,

side of traingle (2) = 2x

base of triangle (2) = 2y

area of traingle (2) = 1/2*2x*2y = 2xy

Ratio of triangle (1) & triangle (2) = 1:4
