Russia-Ukraine crisis update - 3rd Mar 2022 Perimeter of Parallelogram(Area of Parallelogram).Mensuration : Area and Perimeter of the Rectangle Now, area of rectangle EFGH = 100 x 85 = 8500 m 2Īnd area of rectangle ABCD = 90 x 75 = 6750 m 2Īrea of path = Area of rectangle EFGH – Area of rectangle ABCD Find the area of the path.Īrea of the path = Area of rectangle EFGH – Area of rectangle ABCD A path 5 m wide is to be built out around it. So, the width of the rectangular plot is 20 m and its perimeter is 84 m.ģ) A rectangular garden is 90 m long and 75 m broad. Also find its perimeter.Īrea of the rectangle = l x w (where w = width of the rectangular plot Total labour charges for painting the wallģ) Find the breadth of a rectangular plot of land, if its area is 440 m 2 and the length is 22 m. Painting of the wall has to be done excluding the area of the doorĪrea of wall including door = side x sideĪrea of wall excluding door = (121 - 20) m 2 Find the total labour charges for painting the wall if the labour charges for painting 1 m 2 of the wall is $ 2.50. = 26,400 / 10,000 Ģ) A door frame of dimensions 4 m x 5 m is fixed on the wall of dimension 11 m 11 m. Some solved examples on Area of Rectangleġ) Find the area, in hectare, of a field whose length is 240 m and width 110 m. ∴ Distance covered in 5 rounds = 5 x Perimeterīut, the total distance covered is given = 3 km = 3000 m. In completing one round of the field distance covered is equal to the perimeter of the field. A man jogged around it 5 times and covered a distance of 3 km. Since length and width are positive integers in centimeters. Some solved examples on Area and Perimeter of the Rectangleġ)ğind the perimeter of a rectangle whose length and width are 25 m and 15 m respectively.Ģ)How many rectangles can be drawn with 36 cm as the perimeter, given that the sides are positive integers in cm ?
