The length of a rectangle is three times the width and the area is 192 cm find the dimensions of the rectangle
.
Let w = width
from "length of a rectangle is three times the width" we have
3w = length
.
from "the area is 192 cm" we have our equation:
w(3w) = 192
3w^2 = 192
w^2 = 64
w = 8 cm (width)
.
length:
3w = 3(8) = 24 cm (length)
