Question
In the given figure:
Find the area of ∆AEC.
- 25
- 30
- 35
- 40
Hint:
Area of triangle is half of the product of Base and Height of a triangle.
The correct answer is: 30
>>>In General the area of the triangle is the half to the product of base and height of a triangle.
>>>Given That:
>>>>The triangle AEC forms right angled triangle, because it's sides are the Pythagorean triplets.
>>>Therefore, the area of the triangle AEC becomes:
Area =
Area = × 12 × 5
Area = 30
>>>Hence, the area of the triangle is 30 square units.
Area = × 12 × 5
= 30
