If every side of a triangle is doubled, then increase in the area of a triangle is______
Options-
a) 100√2%
b) 200%
c) 300%
d) 400%​

Answer 1

Answer:

Step-by-step explanation:

take ans example and solve

let sides be 3,4,5

here area = 1/2 * 3 * 4 = 6

when we double sides

6,8,10

area = 1/2*6*8 = 24

so 24/6*100 = increase in area

increase in area  = 4*100 = 400%

Answer 2

Answer:

300% is the correct answer
