Question

Find the height of a triangle that has an area of 54 cm2 with the width 3 cm less than its height.

Answer 1

The height of a triangle is 9 cm

What is Triangle?

• A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the display style for a triangle with vertices A, B, and C.
• In Euclidean geometry, any three points that are not collinear produce a singular triangle and a singular plane (i.e. a two-dimensional Euclidean space).
• In other words, every triangle is contained in a plane, and there is only one plane that contains that triangle.
• All triangles are enclosed in a single plane if all of the geometry is the Euclidean plane, however, this is no longer true in higher-dimensional Euclidean spaces.
• Except when otherwise specified, this article discusses triangles in Euclidean geometry, namely the Euclidean plane.

given that

let the height of the triangle be x

then the width is x-3

Area = $\frac{height \times length}{2}$

54 = x(x -3)

$54 = x^2 -3x$

x = 9

height = 9 cm

width = 6cm

Therefore, the height of a triangle is 9 cm.
