Area of a triangle: When we know the sides and angles of a triangle, we may determine its area using several formulas. Learn @ Embibe.
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 ...

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 {...

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 $\frac{1}{2} \times \text{base} \times \text{height}$. ...
Area is thetotal amount of space a 2-D shape (or flat surface) takes up. Every shape in math—that is, every square, rectangle, triangle, parallelogram, trapezoid, etc.—has an area, or a certain amount of space it occupies.
shape类是一个表示形状的抽象类,area()为求图形面积的函数,作为纯虚函数,请从shape类派生出三角形类(triangle)、矩形类(rectangle),并给出具体的求面积函数.然后通过主函数定义三角形类和矩形类的对象,分别求出他们的面积. (注:若三角形的边长分别为a、b和c,则三角形的面积s计算如下,),其中 ) p=(a+b+c...
