Question 15
The perimeter of the triangle shown in the figure below is:
(a) 2x + y
(b) x + 2y
(c) x + y
(d) 2x - y
Option (a).
Perimeter is defined as the total sum of length of all the bounding sides of a planar object.
Length of sides of the given triangle are x, x and y.
Hence, the perimeter of the triangle = x + x + y = 2x + y
