Welcome! In this post, you will learn about few word problems based on decimals.
Problems related to the area of a triangle.
The area is known as the region occupied inside the boundary of a flat object or figure. The measurement is written in square units with the quality unit being square meters (`m^(2)`). For the calculation of area, there are pre-defined formulas for squares, rectangles, circles, triangles, etc. during this article, You'll learn the area of triangle formulas for various sorts of triangles, alongside some example problems.
The area of a triangle is defined because the total region that's enclosed by the three sides of any particular triangle. Basically, it's adequate to half the bottom times height, i.e. A = `\frac{1}{2}` × b × h. Hence, to seek out the world of a tri-sided polygon, we've to understand the bottom (b) and height (h) of it. it's applicable to all or any sorts of triangles, whether it's scalene, isosceles, or equilateral. To be noted, the bottom and height of the Triangulum are perpendicular to every other. The unit of area is calculated in square units (`m^(2)`, `cm^(2)`).
Let's discuss one example related to Q5. In any triangle, if base and height are given then to find its area, we can use the formula Area of triangle = `\frac{1}{2}` Base(b) x Height(h)
