The area of a triangle in coordinate geometry can be calculated if the three vertices of the triangle are given in the coordinate plane. The formula to calculate the area of a triangle is given by 1/2 (x1 (y2 - y3) + x2 (y3 - y1) + x3 (y1 - y2)|.
How can the area of a rectangle be found? To find the area of a rectangle, multiply the length times the width. The area, or flat space inside the rectangle, must be expressed in square units. What is the formula for the area of a triangle? The formula for the area of a triangle ...
Theareaof anequilateral triangleis defined as the region covered within the three sides of the triangle and is expressed in square units. Some important units used to express the area of an equilateral triangle are in2, m2, cm2, yd2, etc. Let us understand the formula that is used to ca...
