x=14.8-(7.3+2.49)
simple, to find the missing length subtract the two given lengths from the perineter

Answer:

Side 3 = 14.8-(2.94+7.3) cm.

Step-by-step explanation:

Since perimeter of any polygon is the sum of its sides.

Therefore perimeter of a triangle is the sum of length of all sides of the triangle.

Or we can represent this as perimeter of a triangle = side 1 + side 2 + side 3

Here perimeter of the triangle = 14.8 cm.

side 1 = 7.3 cm

side 2 = 2.94 cm

Therefore by putting these values in the formula

14.8 = 7.3 + 2.94 + side 3

Side 3 = 14.8 - (7.3 + 2.94)
