Answer:
If the length of a rectangle is x + 5, and the width is x + 3, then its perimeter can be expressed as:
Perimeter = 2(length + width)
P = 2(x + 5 + x + 3)
P = 4x + 16
We are given that the perimeter is 24, so we can set up an equation:
4x + 16 = 24
Solving for x:
4x = 8
x = 2
Now that we know x = 2, we can find the length and width of the rectangle:
Length = x + 5 = 2 + 5 = 7
Width = x + 3 = 2 + 3 = 5
The area of a rectangle is given by:
Area = Length x Width
So the area of this rectangle is:
Area = 7 x 5 = 35
Therefore, the area of the rectangle is 35 square units.
Explanation:
The correct answer is:
Area = Length x Width
Area = (x + 5) x (x + 3)
We know that the perimeter is 24:
Perimeter = 2(Length + Width)
24 = 2[(x + 5) + (x + 3)]
24 = 2(2x + 8)
24 = 4x + 16
8 = 4x
x = 2
So the length and width are:
Length = x + 5 = 7
Width = x + 3 = 5
Therefore, the area of the rectangle is:
Area = Length x Width
Area = 7 x 5
Area = 35
Therefore, the answer is O 35.
