For what value of x is the perimeter of shape 77 cm
Solution:
Given, the figure represents a pentagon.
We have to find the value of x.
Given, the perimeter is 77 cm
We know, perimeter = sum of all sides
77 = (x + 1) + (x + 1) + (2x + 1) + (2x + 2) + (x + 2)
77 = x + x + 2x + 2x + x + 1 + 1 + 1 + 2 + 2
77 = 7x + 7
By transposing,
7x = 77 - 7
7x = 70
x = 70/7
x = 10
Therefore, the value of x is 10 cm.
