Description : If each side of a triangle is doubled,... -Maths 9th
Last Answer : Let a, b, c be the sides of the given triangle and s be its semi-perimeter. Then, s = (a + b + c)/2 ...(i) ∴ Area of the given triangle = root under ( √s(s - a)(s - b)(s - c)) = △, say According to ... - c)) = 4 root under ( √ s(s - a)(s - b)(s - c)) = 4 △ Therefore, the required ratio is 4:1
