Area Formula Worksheets The figure is composed of an equilateral triangle, a rectangle, and a semi circle (half of a circle). using the formula for the area of an equilateral triangle and side length 10: the length and width of the rectangle are 10 in and 4 in respectively, so its area is. a = 10×4 = 40. the area of the semi circle is one half the area of a circle. Area of sectors. a portion of a circle that is covered by two radii (plural of radius) and the corresponding arc is known as the sector of the circle. the area of a sector is computed with the help of the formula: a= θ 360 * πr^2. where θ corresponds to the angle that is formed by the two radii. area of segments.
Area Formula What Are Area Formulas For Different Geometric Shapes Area of a square = base × height. area of a square = s2. a square, technically speaking, is a rectangle (don't remind the rectangle, it's a little sensitive), so we can use the formula for the area of a rectangle to find the area of a square. since a square's base and height are equal, the area of a square is also side length times side length. Let's break the area into two parts: part a is a square: area of a = a 2 = 20m × 20m = 400m 2. part b is a triangle. viewed sideways it has a base of 20m and a height of 14m. 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. sam earns $0.10 per square meter. The area of a figure is the number of squares required to cover it completely, like tiles on a floor. area of a square = side times side. since each side of a square is the same, it can simply be the length of one side squared. if a square has one side of 4 inches, the area would be 4 inches times 4 inches, or 16 square inches. By the formula of area of circle, we know; a = π r 2. a = 22 7 x 7 x 7. a = 154 sq.m. example 2: the side length of a square plot is 5m. find the area of a square plot. solution: given, side length, a = 5m. by the formula of area of a square, we know; area = a 2. a = 5 x 5. a = 25 sq.m. example 3: find the area of the cone, whose radius is 4cm.

Example 1: find the perimeter of a rectangular box, with length as 6 cm and breadth as 4 cm. solution: use the formula, perimeter of a rectangle = 2 (l b) = 2 ( 6 cm 4 cm) = 2 × 10 cm = 20 cm. example 2: how to find the area and perimeter of a square? find the perimeter of a square if the area is 36 cm2. The definition of area in math is the space inside of the shape. in a two dimensional shape, the area must include the units used, which will be squared units (units 2). the shapes pictured in the.
