the length of a small rectangular room is 4 units more than the width, the area of the room is 32 square units. what is the dimensions of the room? help me please!!
change the English into "math" length of a small rectangular room is 4 units more than the width remove most of the words: length is 4 more than width use a letter for the unknown length and the unknown width L is 4 more than W change is to equals L = 4 more than W change more than to "add" L = 4+W
next, area of rectangular room = 32 what is the formula for the area of a rectangle ? see http://www.mathopenref.com/rectanglearea.html it is area = L*W in this case, we know the area is 32, so we have L*W= 32
you now have 2 equations and 2 unknowns, so you can solve them L = 4+W L*W= 32 can you solve these ?
yes i can thanks
