we know that
area of rectangle A=L*W
A=L*W------> solve for W
W=A/L

case 1) L=5 cm A=31.25 cm²
W=A/L-----> 31.25/5----> W=6.25 cm
the answer part 1) is W=6.25 cm


case 2) L=9.25 cm A=55.5 cm²
W=A/L----->55.5/9.25----> W=6 cm
the answer part 2) is W=6 cm

case 3) L=7.5 cm A=48.75 cm²
W=A/L-----> 48.75/7.5----> W=6.5 cm
the answer part 3) is W=6.5 cm

case 4) L=5 cm A=44 cm²
W=A/L-----> 44/5----> W=8.8 cm
the answer part 4) is W=8.8 cm
