Do you know how to calculate the area of triangles and parallelograms? Is there any short and simple method to do so? Well, there are multiple ways in which you can find out these areas. Let’s study the theorems mentioned in the section below to calculate the area of triangles and parallelograms.

**FAQs on Area of Triangles and Parallelograms**

**Question 1: What is the area of the isosceles triangle?**

**Answer:** For finding the area of an isosceles triangle using the lengths of the sides, label the lengths of each side, the base, and the height (if provided). After that, use the equation of area = ½ base times height (Area = ½ × base × height).

**Question 2: State the formula to find the area of the scalene triangle?**

**Answer:** The area of a scalene triangle can be found using the formula ½ base ties the height (that is ½ × base × height). Besides, if you know the length of all the three sides then you can calculate the area using the Heron’s Formula without finding the height.

**Question 3: What is the area of an isosceles right triangle?**

**Answer:** The formula for finding the area of a right-angled isosceles triangle is ½ × a^{2}, where ‘a’ is the length of the equal sides. For example, if the length of the equal side is 8 cm then the area will be:

½ × a^{2} = ½ × 8^{2}

∴ ½ × 64 = 32 cm.

**Question 4: How to find the area of an obtuse triangle?**

**Answer:** For finding the area of an obtuse triangle, firstly finds the height of the triangle (if not known) then find the length of the base. However, you can take any side as a base in an obtuse triangle. After that use the formula ½ × base × height.
