How can I find the area of a triangle with 3inches, 5inches, and 4inches?

Given:

Sides of a triangle are

a = 3 in, b = 4 in and c = 5 in

To find:

The area of the triangle.

Solution:

Using Heron's formula:

S = 6 in

in²

Area of a triangle is 6 in².

Given:

Given that the sides of the triangle are 3 inches, 5 inches and 4 inches.

We need to determine the area of the triangle.

Area of the triangle:

The area of triangle can be determined using the formula,

where b is the base of the triangle and h is the height of the triangle.

From the figure, it is obvious that the base of the triangle is 4 inches and the height of the triangle is 3 inches.

Substituting b = 4 and h = 3 in the above formula, we get;

Thus, the area of the triangle is 6 square inches.

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
