You can put this solution on YOUR website! The length of a rectangle is 4m greater than the width. The area of the rectangle is . What is the length and the width of the rectangle?
Let x = length of the rectangle
y = width of the rectangle
Representation :
x = y + 4
Formula of the area of a rectangle A = lw therefore, A= xy
Solution:
A =
96 = y (y + 4)
96 =
0 =
0 = (y + 12) (y - 8)
0 = y + 12 | 0 = y - 8
y = -12 | y = 8
length and width should not be negative.. the answer for the width is 8m. Length is 4m greater than the width so 8 + 4 = 12m for the length.
answer :
x = 12m and y = 8m
