Question

find the area and perimeter of right angle triangle base is 4m and height is 6 m
​

Answer 1

Answer:

Area = 12 m²

Perimeter = 17.21 m

Step-by-step explanation:

base = 4 m

height = 6 m

The height and the base of the triangle has already been given. Therefore, we can use the formula :

$\frac{1}{2}$ x base x height

= $\frac{1}{2}$ x 4 x 6

= 12 m²

The perimeter of a triangle is a + b + c.

We need to find the hypotenuse (let us name it c).

Using the pythagoras' theorem,

AC² = BC² + AB²

where AC is the hypotenuse, BC is the base and AB is the height.

c² = a² + b²

c² = 4² + 6²

c² = 16 + 36

c² = 52

Therefore, c = √52 , which is 7.21 m

Therefore, the perimeter of the triangle would be

4 + 6 + 7.21

= 17.21 m

Ugh, I'm not a math whizz (never got over 80 in maths) and I'm always doing careless errors, but I hope this helped.
