First, put 0.18 over 100 because there are 2 digits in the decimal, so you convert it to 18/100. Then, simplify it, and because the GCF is 2, divide the numerator and denominator. The final fraction ins 9/50.
The area of the rectangle is length times width, that is A = L*W The problem requires the width so W = A/L Given that A = 437 sq. cm and L = 19 cm, therefore W = 437/19 = 23 cm
