Answer:
7 ft
Step-by-step explanation:
Perimeter of a rectangle is denoted by the formula: , where l is the length and w is the width.
We know that P = 20 and that w = 3. So, let's plug these values in:
Isolate the variable by subtracting 6 from both sides and dividing by 2:
Thus, the answer is 7 feet.
Hope this helps!
7 feet
Perimeter = 2(length + width)
20 = 2(length + 3)
length + 3 = 10
length = 7 feet
The answers are proved by replacing x with 3 and 6 respectively.
