The area of a two-dimensional shape like a triangle or a rectangle measures the flat space inside the shape. To find the area of a rectangle, two dimensions must be known: the rectangle's length and width. The area of a rectangle formula is: {eq}Area\ = \ length\ \times\ width {...
Trapezoids and triangles are two geometric shapes. A triangle is any three-sided figure. A trapezoid is a four-sided figure with one pair of parallel lines. You might want to calculate the area of a triangle or trapezoid if you had a room in that shape and you wanted to put down new ...

FAQs about calculating the area of a triangle What is the area of a triangle? The area of a triangle is the space enclosed within the three sides of any basic triangular shape. Calculating the area tells us just how much space these polygons take up, which is helpful when trying to unde...
“area” in general. The measurement is done in square units, with square metres being the usual unit (m2). There are pre-defined formulas for calculating area for squares, rectangles, circles, triangles, and other shapes. We will study the area of triangle formulae for several sorts of ...
Area of a Square= Side x Side = s2sq. units For example, if we have a square whose one side is 6 cm, its area would be calculated as Area = Side x Side = 6 x 6 = 36 cm2 Area of a Triangle A triangle is a polygon that is made of three edges and three vertices. The vert...
Area of a triangle is the region covered by its three sides in a plane. Area of a triangle is equal to half of product of its base and height. Find the area using heron's formulas and SAS condition, with examples at BYJU'S.
Calculate the area of shape.Now let’s try finding the area of this triangle with base $= 20$ mm and height $= 5$ cm. The formula to find the area of a triangle is $\frac{1}{2} \times \text{base} \times \text{height}$. ...
