Answer:
Width = 4 cm
Length = 16 cm
Step-by-step explanation:
We are given;
- Perimeter = 40 cm
- Assuming the width is x
- Then, length is 2x + 8 ( 8 more than twice the width)
We are required to determine the dimensions of the rectangle;
- We need to know that the perimeter of the rectangle is given by;
- Perimeter = 2 (length + width)
In this case;
2 ( 2x + 8 + x) = 40
2 ( 3x + 8 ) = 40
6x + 16 = 40
6x = 24
x = 4
Thus; the dimensions of the rectangle are;
Width = 4 cm, and
Length = 16 cm
