Area And Perimeter Of Triangle Formula Area and perimeter for all shapes. there are many types of shapes. the most common ones are square, triangle, rectangle, circle etc. to know the area and perimeter of all these, we need different formulas. perimeter and area of a rectangle. a rectangle is a figure shape with opposite sides equal and all angles equal to 90 degrees. Activity 10 5: area of triangles name: formula for the area of a triangle: 1 or 2 2 bh a bh= (half of the formula for a parallelogram.) example: the height is measured straight up from the base. the height of this triangle is 5 in. 2 2 6 5 2 15 in. bh a a a = • = = find the area of each triangle using the formula above. show all steps on a.

Perimeter Of A Triangle Formula Examples Curvebreakers Frequently asked questions (faq) – area and perimeter of triangles. q.1. what is the formula of the perimeter of the triangle? ans: a triangle is a two dimensional closed figure having three sides and three corners. the perimeter of a triangle is calculated by simply adding the length of all three sides. 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 are equal. The area of a parallelogram is equal to the base multiplied by the height: a = bh a = b h. the height of a parallelogram is always perpendicular to the base (the sides are not the height). area of a triangle. the area of a triangle is half the area of a parallelogram. hence the formula: a = 1 2bh a = 1 2 b h or a = bh 2 a = b h 2. A triangle is the simplest polygon with three sides. all other polygons have more than three sides. the word perimeter is taken from greek words meaning “around measure.”. the area a of an equilateral triangle of side length s cm can be calculated using the formula a=34× s2. the value of 3 is about 1.73.
