Answer:
- The length = x = 15 units
- The width = x-5 = 10 units
Step-by-step explanation:
Let 'x' be the length of a rectangle
As the width of a rectangle is 5 units less than the length.
so
width of rectangle will be = w = x - 5 units
Area = 150 square units
Using the formula
Area = length × width



Subtract 50 from both sides



if



As length can not be negative. so
x = 15 units
Hence,
The length = x = 15 units
The width = x-5 = 15-5 = 10 units
To answer this, we need to know the expression for the area of a square which is the square of its side length or:
Area = a²
Solving for the side length,
a = √area
a = √144x²
a = 12x
Therefore, the side length is 12x.
