Question 1208965
<font color=black size=3>
w = width
3w = three times the width
3w+7 = seven more than the previous amount = length


perimeter = 2*(length+width)
perimeter = 2*(3w+7 + w)
2*(4w+7) = 38
8w+14 = 38
8w = 38-14
8w = 24
w = 24/8
w = 3 cm is the width
length = 3w+7 = 3*3+7 = 16 cm


area = length*width = 16*3 = <font color=red>48 square centimeters</font>
