Thank you for your interest in this resource from Rise over Run. A parallelogram has base length of 16cm and the distance between the base and its opposite side is 7.5cm. A rectangle is a figure/shape with opposite sides equal and all angles equal to 90 degrees. Area = L * W . A triangle is a shape with three angles and three straight lines. Perimeter of a Trapezoid = a + b1 + b2 + c With regards to the question base = 6 cm. For Example, to fence the garden at your house, the length required of the material for fencing is the perimeter of the garden. For a polygon with straight sides this is the sum of all sides. Area and perimeter, in Maths, are the two important properties of two-dimensional figures. Example: the perimeter of this rectangle is 7+3+7+3 = 20. We’ll start with the area and perimeter of rectangles. Area is the region bounded by the shape of an object. Solution: Given, radius = 21cm. Area of rectangle = l × b; (l and b are the length and breadth of rectangle) Diagonal of rectangle = √(l² + b²) Perimeter and Area of the Square: Perimeter of square = 4 × S. Different shapes have different areas. The next step is to determine the length of 1st diagonal which is equivalent to the distance from A to C. Study of Tissues and Diversity in Shapes and Sizes of Plant and Animal Cells, Vedantu For perimeter = 2(a+b) For area = a x b. We have, Area formula A = length x width = 15 x 6 = 90 m 2 And Perimeter formula P = 2 (length + width) = 2 x (15 + 6) = 2 x 21 = 42 m. Quiz Time. A Square is a figure/shape with all four sides equal and all angles equal to 90 degrees. Note: Here value of pi is either 22/7 or 3.14. While it's a good idea to memorize these formulas, here is a list of perimeter, circumference, and surface area formulas to use as a handy reference. The area = ( Perimeter x Apothem ) / 2 . You can use any one of them if not mentioned in the question. Area of B = ½b × h = ½ × 20m × 14m = 140m 2 So the total area is: Area = Area of A + Area of B = 400m 2 + 140m 2 = 540m 2 Image will be uploaded soon. Therefore, Area = length x width = 12 x 10 = 120 sq.m. (i) According to the formula 2 π r = 2 x 3.14 x 14 cm = 87.92 cm. If a rhombus has base and height 10 cm and 7 cm respectively, calculate its area. of tiles required to cover the whole floor.
