what will be the percentage of area of a triangle if the side is doubled??
Answers
Answer:
Let the height of the triangle be : 10 cm
∆ABC is a traingle.
Base be : 5 cm
We know,
Area of triangle : 1/2 × base × perpendicular height
Hence,
1/2 × 5 × 10 = 25 cm² (Area of the first triangle).
According to user's doubt,
If the sides are doubled, was percent of area would be increased?
2nd Answer:-
Second Triangle:
New height : 10 × 2 = 20 cm
New base : 5 × 2 = 10 cm
Hence,
New area = 1/2 × 10 × 20 = 100 cm²
Hence, difference between the first area and the second one = 100 - 25 cm² = 75 cm²
Now, finding the increased percentage:
75/25 × 100% = 75 × 4% = 300%
REQUIRED ANSWER:
If the sides of a triangle are doubled, the area increases by 300%.
Answer:
Let the height of the triangle be : 10 cm
∆ABC is a traingle.
Base is : 5 cm
We know,
Area of triangle : 1/2 × base × perpendicular height
therefore
1/2 × 5 × 10 = 25 cm² (Area of the first triangle).

here, finding the increased percentage:
75/25 × 100% = 75 × 4% = 300%
