Area of triangle
 1) Find the area of an acute triangle with a base of 15 cm and a height of 4 cm. 40 cm2 20 cm2 30 cm2 60 cm2

 2) A triangle and a parallelogram have the same base and the same area. If the sides of the triangle are 15 cm, 14 cm and 13 cm, and the parallelogram stands on the base 15 cm, find the height of the parallelogram 5.4cm 5.5cm 5.6cm 5.7cm

 3) How much area of a triangle will increase if its each side is doubled. Calculate the percentage increase 200% 300% 400% 500%

 4) If each side of the triangles is doubled ,Area of the triangle will become? 2 times 4 times 3 times 7 times

 5) Find out the area of a right angle triangle which has base as 21 cm and perpendicular as 42 cm. 440 cm2 441 cm2 442 cm2 443 cm2

 6) The formula to calculate the area of a triangle with base b and height h is: Area = b * h Area = b + h Area = (b * h) / 2 Area = (b + h) / 2

 7) The area of an equilateral triangle with side length s is given by the formula: Area = s^2 Area = (s * sqrt(3)) / 4 Area = (s * sqrt(3)) / 2 Area = (s^2 * sqrt(3)) / 4

 8) The area of a triangle with sides of lengths a, b, and c, and semi-perimeter s, can be calculated using: Area = sqrt(s * (s - a) * (s - b) * (s - c)) Area = s * (s - a) * (s - b) * (s - c) Area = (a + b + c) / 2 Area = (a * b * c) / 2

 9) If the base of a triangle is 8 units and the corresponding height is 5 units, the area of the triangle is: 16 square units 13 square units 20 square units 40 square units

 10) The area of a right-angled triangle with legs of lengths a and b is given by the formula: Area = sqrt(a^2 + b^2) Area = (a * b) / 2 Area = a + b Area = (a + b) / 2
