The length and width of the rectangle are 15in and 8in respectively
Area of rectangle
The formula for calculating the area of a rectangle is expressed as:
A = lw
- l is the length
- w is the width
If the width of a rectangle is 7 inches less than its length, then;
w = l - 7
A = 120 square inches
On substituting;
120 = (l-7)l
120 = l² - 7l
l² - 7l - 120 = 0
On factorizing, l = 15 in
w = A/l
w = 120/15
w = 8cm
Hence the length and width of the rectangle are 15in and 8in respectively
