The ratio of length to width is
5 : 4 = length : (35 cm)
4 × length = 35 × 5 cm
length = 35 × 5 / 4 cm
length = 43.75 cm
5 : 4 = length : (35 cm)
4 × length = 35 × 5 cm
length = 35 × 5 / 4 cm
length = 43.75 cm

5/4 = x/35
x = 175/4 cm
x = 175/4 cm

l:w :: 5:4 :: L:35
L/35 = 5/4
L = 35 x 5 / 4
L = 43.75 cm
L/35 = 5/4
L = 35 x 5 / 4
L = 43.75 cm

The ratio of the length of a rectangle
to its width is 5 : 4.
If the width is 35 cm,
the length is 43.75 feet.
to its width is 5 : 4.
If the width is 35 cm,
the length is 43.75 feet.

5:4 is 5 + 4 = 9 parts.
If width = 35 = 4 parts
1 part = 35/4 = 8.75cm
Length = 5 parts = 5 x 8.75 = 43.75cm
If width = 35 = 4 parts
1 part = 35/4 = 8.75cm
Length = 5 parts = 5 x 8.75 = 43.75cm

L = (5/4)*35 = 43.75
You could have done that

4x/5 = 35 4x = 175 x=43.75 cm
check it out.
35/4 = 8.75
43.75/5 = 8.75
check it out.
35/4 = 8.75
43.75/5 = 8.75
