Answer:
Step-by-step explanation:
Width = w
Length = 3w
Area = 243 square units
length *width = 243
3w * w = 243
3w² = 243
The equation that can be used to find the width of the rectangle is 3w² = 243.
A rectangle is a polygon having four sides , The opposite sides are equal to each other and measure of all the angles is 90 degrees.
It is given that
A rectangle's length is three times its width, w.
l = 3w
Its area is 243 square units.
Area of a rectangle is given by
length * breadth
l*w
3w*w = 243
3w² = 243
equation that can be used to find the width of the rectangle is 3w² = 243.
