Area and Perimeter of Triangles, Parallelograms, and Trapezoids Worksheets

How to Find Area and Perimeter of Triangle, Parallelogram, and Trapezoid? The perimeter of a shape is the length of its boundary, usually measured in the same units as that of length. Perimeter is measured in m, cm, mm. The area is the measurement of the area enclosed by the plane region. Area is measured in square units Area and Perimeter of the Triangle - For a triangle, we can find the perimeter by adding the lengths of its three sides. P = (a + b + c). Where a, b, and c are the three sides of a triangle. Area of the triangle is the space occupied by the shape. Area of the triangle is half the area of the rectangle. A = 1/2 (l x w). Where l is the length of the sides, and w is the width of the triangle. Area and Perimeter of Parallelogram - A parallelogram is a quadrilateral that has two parallel opposite sides. In a parallelogram, the two opposite sides and the angles are congruent, while the consecutive angles are supplementary. To find the area of a parallelogram, we have the formula: A = b x h. Where b is the base length, and h is the height. The perimeter of a parallelogram is the sum of its all four sides. P = a + b + c + d. Where a, b, c, and d are the four sides of the parallelogram. Area and Perimeter of Trapezoid - A trapezoid is a quadrilateral with one pair of parallel sides. The non-parallel sides of the trapezoid are known as the legs, and the parallel sides are known as the bases. The area of the trapezoid is calculated by the formula: A = 1/2 (b1 + b2) x h. Where b1 and b2 are the bases, and h is the height of the trapezoid. The perimeter of a trapezoid is the sum of all four sides. P = a + b + c + d. Where a, b, c, and d are the four sides of the trapezoid.
