How to solve the question step by step
1 answer:
Length = L
New length = L+0.1L= 1.1 L
Width = W
New width = W - (W/100)p= W-pW/100= (100W-pW)/100=W(100-p)/100
Area =A = LW
New area = A - 0.12A = 0.88A
New area = new width*new length = 1.1L*W(100-p)/100 = 1.1A(100-p)/100
New area = 0.88A
New area = 1.1A(100-p)/100
1.1A(100-p)/100 = 0.88A
1.1(100-p)/100 = 0.88
1.1(100 - p) = 88
100 - p = 80
p = 20
Answer C) 20.
