5 days ago · The formula for the area of the triangle can be expressed as Area = A = ½ (b x h) square units, where h is the height of the triangle and b is the base of the triangle. The area of the triangle depends on the type of triangle. There are different formulas for a right-angled triangle, isosceles triangle, and equilateral triangle.

What is the area of a triangle with a base of 9 inches and a height of 8 inches? 677. If a triangle has a base that's 3 meters long and a height that's 23 meters in length, what is its area? 3 678.
5 days ago · The side to which the perpendicular meets is called as the base of a triangle. Area and Perimeter Formula of Triangle : Area of a triangle = 1/2 × (base) × (height) Perimeter of a triangle = Sum of all three sides. Rectangle. A rectangle is a four sided polygon having opposite sides equal and parallel. All the angles of a rectangle ...
4 days ago · Hint: Here, we need to find the perimeter of the given isosceles triangle. First, we will use the formula for the area of a triangle to find the height of the triangle. Then, we will use congruence and Pythagoras’s theorem to find the lengths of the remaining sides of the triangle.
3 days ago · For an isosceles triangle if the given two sides have the same length then for calculating the length of the third side of the triangle, we can use a trigonometric formula for finding the length of the unknown side of the triangle, which is $l=2\cdot a\cdot sin\left( \dfrac{\theta }{2} \right)$
23 hours ago · Triangles have many types based on the length of the sides and on the angles. A triangle whose sides are all the same length is an equilateral triangle, [3] a triangle with two sides having the same length is an isosceles triangle, [4] [a] and a triangle with three different-length sides is a scalene triangle. [7]
