ANSWER:
The length of the third side of a triangular playground at a shopping mall is 15 feet.
SOLUTION:
Given, perimeter of a triangular playground at a shopping mall = 48 feet
Length of one of the side of that triangular playground = 19 feet
Length of another side of that triangular playground = 14 feet
Now, we need to find the length of the third side of the triangle.
We know that the formula for perimeter of triangle is given as
p = a + b + c
Where, p is the perimeter of the triangle
a is the length of first side of triangle
b is the length of second side of triangle
c is the length of third side of triangle
We need to find the length of third side
Let a = 19 feet ; b = 14feet ; c =?
p = a + b + c
48 = 19 + 14 + c
48 = 33 + c
c = 48 – 33
c = 15feet
Hence, length of the third side of a triangular playground at a shopping mall is 15 feet
