Answer:
<u>If P is 30 units and l is 10 units, w is 5 units</u>
Step-by-step explanation:
1. Let's check the information given to resolve the question:
P = 2l + 2w
If P is 30 units and l is 10 units, w is units
2. Replacing with the values:
P = 2l + 2w
30 = 2 (10) + 2w
30 = 20 + 2w
-2w = 20 -30 (Subtracting 2w and - 30 to both sides)
-2w = - 10
2w = 10 (Multiplying by - 1 at both sides)
<u>w = 5 (Dividing by 2 at both sides)</u>
<u>If P is 30 units and l is 10 units, w is 5 units</u>
