Answer:
length = 56cm
width = 70cm
Step-by-step explanation:
Given:
- w = l + 14 cm
- Perimeter (P) = 2(l + w)
Where:
[tex]\boxed{P = (2(l+w)}[/tex]
252 cm = 2l + 2(l +14cm)
252cm = 2l + 2l + 28 cm
252cm = 4l + 28cm
4l = 252cm - 28cm
4l = 224cm
l = 224cm/4
l = 56cm
Substituting Length of 56cm into the main formula
P = 2(l + w)
252cm = 2(56 + w)
252cm = 112cm + 2w
2w = 252cm - 112cm
2w = 140cm
w = 140cm/2
w = 70cm
Therefore, the values of length and width simplify to:
- length = 56cm
- width = 70cm
