Area of weird shapes6/22/2023 ![]() ![]() ![]() Irregular shapes are those shapes that do not have equal sides or equal angles. The area of irregular shapes is defined as the amount of space that is covered by an irregular shape. Therefore, the area of the given irregular shape is 159.25 square units.įAQs on Area of Irregular Shapes What is the Area of Irregular Shapes? ⇒ Area of the given irregular shape = 48 + 39.25 + 24 + 48 = 159.25 square units. Now, let us find the area of the irregular shape using the area of the regular shapes:Īrea of the given irregular shape = Area of the rectangle 'P' + Area of the semicircle 'Q' + Area of the triangle 'R' + Area of the rectangle 'S'. Area of rectangle 'S' = Length × Breadth = 6 × 8 = 48 square units.⇒ Area of the triangle 'R' = 1/2 × 8 × 6 = 24 square units Area of the triangle 'R' = 1/2 × Base × Height.Area of semicircle 'Q' = πr 2/2 = (3.14 × 5 2)/2 (taking π = 3.14 and the diameter of the semicircle as 10 after using the pythagoras theorem in figure R).Area of rectangle 'P' = Length × Width = 6 × 8 = 48 square units.Let us find the area of each shape first. To find the area of the irregular shape, we will add up the area of the shapes that come together to form this irregular shape: Therefore, the area of the given irregular shape = Sum of all the unit squares falling under the irregular shape.įind the area of the given irregular shape. We can use this method for shapes which have curves like the one shown in the following figure. So, in this case we get an approximate area of the irregular shape. It should be noted that while calculating the area for a more accurate estimate we count the square as “1” if the shaded region covers more than half of each square. The total number of unit squares falling within the shape determines the total area. Method 2: In some cases, the irregular shape is divided into small unit squares or grids. ⇒ Area of the given irregular shape = area of A + area of B + area of C + area of D + area of E + area of F + area of G Therefore, the area of the given irregular shape = Area of all the polygons that form the irregular shape. Method 1: As we discussed earlier, to find the area of irregular shapes, we can divide the irregular shape into familiar polygons and then find the area of each individual polygon. We use different methods to find the area in such cases. There is no direct formula to calculate the area of an irregular shape. Formula for Finding the Area of Irregular Shapes ![]()
