P=2l+2w w=7 p=42 what is l
2 answers:
Answer:
l = 14
Step-by-step explanation:
Given
p = 2l + 2w and w = 7, p = 42, substitute values into formula
42 = 2l + (2 × 7), that is
42 = 2l + 14 ( subtract 14 from both sides )
28 = 2l ( divide both sides by 2 )
14 = l or l = 14
Answer:
p=98
Step-by-step explanation:
p= 2(7)+2(42)
p= 14+84
p= 98
l= 14
