The length of the side AD is 42 units.
How to find the perimeter of a rectangle?
The perimeter of a rectangle can be found by adding all lengths and widths of the rectangle.
It can be done as shown below:
Perimeter = 2(length + width)
We can find the length of the side as shown below:
A rectangle is given in the figure.
The length of a rectangle is given to be:
4z + 2
The wide of the rectangle is given to be:
3z + 3
The perimeter of the rectangle is 150 units.
Therefore, we can form the equation as shown below:
Perimeter = 2*(length + width)
150 = 2*(4z + 2 + 3z + 3)
150 = 2*(7z + 5)
150 = 14z + 10
150 - 10 = 14z
14z = 140
z = 10
The length of side AD = 4z + 2
= 4(10) + 2
= 40 + 2
= 42
Therefore, we have found the length of the side AD to be 42 units.
