# Area formula

Area formulas of square, rectangle, parallelogram, rhombus, kite, triangle, regular polygon, trapezoid, circle, ellipse, how to use the area formulas, examples and . The most basic area formula is the formula for the area of a rectanglegiven a rectangle with length l and width w, the formula for the area is: a = lw (rectangle) that is, the area of the rectangle is the length multiplied by the width. Geometry formulas areas and perimeters figure sketch area perimeter square a = s2 p = 4s rectangle a = lw p = 2l + 2w. Let's go over these area formulas one more time area of a rectangle = base × height area of a square = base × height area of a square = s 2 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.

Area formula the area of a trapezoid is given by the formula where b1, b2 are the lengths of each base h is the altitude (height) recall that the bases are the two parallel sides of the trapezoid. Perimeter and surface area formulas are part of the math used in common science calculations you 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 a rectangle is a four-sided figure with all interior . Area formula the area of a square is given by the formula but since the width and height are by definition the same, the formula is usually written as where s is the length of one side. Area formulas and perimeter formulas are formulas that pop up often in homework problems this list has formulas for many shapes you may encounter.

Example: what is the area of this rectangle the formula is: area = w × h w = width h = height we know w = 5 and h = 3, so: area = 5 × 3 = 15. Area formulas for all geometric figures let the lengths of the both parallel sides of a trapezoid be a and b and the distance between them is h (the trapezoid altitude) the area is given by the formula:. Free geometry lesson with formulas and diagrams to calculate the area of common polygon shapes. Lindsay finds the area of a rectangle both by counting unit squares and multiplying side lengths.

Homework resources in area formulas - geometry - math this geometry help reference sheet contains the circumference and area formulas for the following shapes: square, rectangle, circle, triangle, parallelogram, and trapezoid. The area of any trapezoid with base side lengths b1 and b2 and height h is given by the formula a = h(b1 + b2)/2 the base sides are the trapezoid's two parallel sides the trapezoid's height is the length of a perpendicular line drawn between the two base sides the formula for the area of a .
