find the perimeter of a triangle with sides 3z-2x-y,4x+y-2z and x+y+z. class 7, subject maths.
plz this question ans step by step .
Answers
Given that -
✠ 1st side of triangle = 3z - 2x - y
✠ 2nd side of triangle = 4x + y - 2z
✠ 3rd side of triangle = x + y + z.
To find -
✠ Perimeter of triangle.
Solution -
✠ Perimeter of triangle = +2z + 3x + 2y
Using concept -
Formula to find perimeter of triangle.
Using formula -
Perimeter of triangle = a + b + c
Where,
☃️ a denotes 1st side
☃️ b denotes 2nd side
☃️ c denotes third side
Full solution -
~ Let us put the values according to the using formula..!
⇢ Perimeter of triangle = a + b + c
⇢ Perimeter of triangle = (3z - 2x - y) + (4x + y - 2z) + (x + y + z)
⇢ Perimeter of triangle = +2z + 3x + 2y
Working note - (Below or attachment)
+3z - 2x - 1y
-2z + 4x + 1y
-1z + 1x + 1y
___________
+2z + 3x + 2y
___________
Answer:
Perimeter of a triangle
=sum of its sides
=(2y+3z+z−y+4y−2z)
=(5y+2z)
