6 The perimeter of a triangle with vertices (0, 4), (0, 0) and (3, 0) is (a) 5 units (b) 12 units (c) 11 units (d) (7 + 5) units

Answer:

We can find the length of each side of the triangle by using the distance formula:

Distance between (0,4) and (0,0) is 4 units (this is the length of the left side of the triangle).

Distance between (0,0) and (3,0) is 3 units (this is the length of the base of the triangle).

Distance between (3,0) and (0,4) is 5 units (this is the length of the right side of the triangle).

Therefore, the perimeter of the triangle is the sum of the lengths of all sides:

4 + 3 + 5 = 12

So the correct option is (b) 12 units.
