Answer: (a) Length = w + 5
Answer: (b) 2 (w + 5) + 2w > 30
Answer: (c) w > 5
Explanation:
w = width
Length = 5mm longer.
Length = w + 5
=======> Length = w + 5
Perimeter = 2 (Length) + 2(Width)
Perimeter =2 (w + 5) + 2w > 30
=======> 2 (w + 5) + 2w > 30
2 (w + 5) + 2w > 30
2w + 10 + 2w > 30
4w > 20
w > 5
=======> w > 5
