Answer:

7 ft

Step-by-step explanation:

Perimeter of a rectangle is denoted by the formula: P=2l+2w , 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:

20 = 2l+2*3=2l+6

Isolate the variable l by subtracting 6 from both sides and dividing by 2:

2l=20-6=14

l=7

Thus, the answer is 7 feet.

Hope this helps!

Answer:

7 feet

Step-by-step explanation:

Perimeter = 2(length + width)

20 = 2(length + 3)

length + 3 = 10

length = 7 feet
