Answer :
let x = new width
18.6/1.5 = 6.2/x
cross multiply and solve for x
18.6x = 6.2 * 1.5
18.6x = 9.3
Divide both sides by 18.6
18.6x/18.6 = 9.3/18.6
Simplify
x =0.5
So when height = 6.2, width = 0.5
18.6/1.5 = 6.2/x
cross multiply and solve for x
18.6x = 6.2 * 1.5
18.6x = 9.3
Divide both sides by 18.6
18.6x/18.6 = 9.3/18.6
Simplify
x =0.5
So when height = 6.2, width = 0.5
