What is rectangular area formula?
The area of a rectangle (A) is the product of its length ‘a’ and width or breadth ‘b’. So, Area of Rectangle = (a × b) square units.
What are the formulas for finding the area of a triangle?
For any given triangle, where the base of the triangle is ‘b’ and height is ‘h’, the area of the triangle can be calculated by the formula, A = 1/2 (b × h).
What is the area of rectangle square triangle?
Area is the size of a two-dimensional surface….Area Formulas.
| Figures | Formula | Variables |
|---|---|---|
| Square | Area = $a^{2}$ | a = sides of square |
| Triangle | Area = $\frac{1}{2}$bh | b = base h = height |
| Circle | Area = $\pi$$r^{2}$ | r = radius of circle |
| Trapezoid | Area =$\frac{1}{2}$(a + b)h | a = base 1 b = base 2 h = vertical height |
Do 2 triangles make a rectangle?
Figure 9.7. 10 – A rectangle can be divided into two triangles of equal area. The area of each triangle is one-half the area of the rectangle.
How many triangles are in a rectangle?
four isosceles triangles
Rectangle. A rectangle has opposite sides which are equal and parallel. It also has four right angles. The diagonals are equal and split a rectangle into four isosceles triangles.
What shape is a rectangle and a triangle?
A trapezium is a four sided figure with two parallel sides. The lines that have been added show that a trapezium is made up of a rectangle and 2 triangles. The area can be found by adding together the area of the rectangle and the two triangles.
Can a rectangle and a triangle have the same area?
A rectangle and a triangle have the same area. When placed on the same level, the tip of the triangle touches the top edge of the rectangle. What is the base of the triangle if the area of the…
What is the equation for the area of a triangle?
Area of a triangle. The formula for the area of a triangle is height x π x (radius / 2) 2, where (radius / 2) is the radius of the base (d = 2 x r), so another way to write it is height x π x radius 2.
How do you calculate the base of a triangle?
Finding the Base. Using the Pythagorean theorem, you can find the base, a, of a right triangle if you know the lengths of the height, b, and the hypotenuse. Since the hypotenuse squared is equal to the height squared plus the base squared, then: a^2 = c^2 – b^2.
What is the area of a square triangle?
There are two easy ways to find the square footage (Area) of a triangle: Area = 1/2 base * height. Area = f(a,b,c) (the length of the three sides)
