Answer 1

Answer:

L= 0.83 in

Step-by-step explanation:

Width= 1.2 in when length = 1 in

Required

Determine the length when width = 1 in

First, we need to determine the ratio

Ratio = $\frac{Width}{Length}$

Ratio = $\frac{1.2}{1}$

Ratio = 1.2 ---(1)

Let the required length be represented with L

So:

Ratio = $\frac{Width}{Length}$

Ratio = $\frac{1}{L}$ ---(2)

Equate (1) and (2)

$\frac{1}{L}$ = 1.2

Multiply through by 1.2

L * $\frac{1}{L}$ = 1.2 * L

1 = 1.2 * L

Divide through by 1.2

L = $\frac{1}{1.2}$

L = 0.83 in (Approximated)
