## What is the formula for the area?

The most basic area formula is the formula for the area of a rectangle. Given 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.

## What is the area of quadrilateral?

To find the area of a rectangle, you need two measurements: the width, or base (the longer side of the rectangle), and the length, or height (the shorter side of the rectangle). Then, just multiply them together to get the area. In other words: Area = base × height, or A = b × h for short.

## What is the formula of quadrilateral?

A quadrilateral is a closed figure that has four sides in it. The interior angles add up to 360 degrees. Also, the opposite sides are parallel and opposite angles are equal.

## What is the 30 60 90 triangle formula?

It turns out that in a 30-60-90 triangle, you can find the measure of any of the three sides, simply by knowing the measure of at least one side in the triangle. The hypotenuse is equal to twice the length of the shorter leg, which is the side across from the 30 degree angle.

## What is the formula for finding the area of an isosceles triangle?

To find the area of an isosceles triangle using the lengths of the sides, label the lengths of each side, the base, and the height if it’s provided. Then, use the equation Area = ½ base times height to find the area.

## What is the formula for finding the area of an equilateral triangle?

In general, the height of an equilateral triangle is equal to √3 / 2 times a side of the equilateral triangle. The area of an equilateral triangle is equal to 1/2 * √3s/ 2 * s = √3s2/4.
