Jonathan is putting a border around a right triangle and needs to figure out the triangle's height. If the triangle has a base length of 4 cm and a total area of 24 cm², what is the height?

Answers

Step-by-step explanation:

formula to find area of a triangle:

A=1/2 × base × height(h)

insert the values into the formula:

24=1/2 × 4 × h

solve for h :

24=2h

24/2=h

h = 12 cm ( Ans )

The height of triangle will be 12 cm.

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

The triangle has a base length of 4 cm.

And, A total area of 24 cm².

Now,

We know that;

Area of right triangle = 1/2 × Base × Height

⇒ 24 = 1/2 × 4 × h

⇒ 24 = 2 × h

⇒ h = 24 / 2

⇒ h = 12 cm

Thus, The height of triangle = 12 cm.
