Answer:
Length=15 cm
Width=13 cm
Step-by-step explanation:
-Let x be the width dimension, the length will be (x-2)
-The area of a rectangle is given by the formula;
#We substitute the length and width values and equate to the given area:
#Rewrite as a quadratic and solve for x:
Since dimensions are always positve, the x value is 15
x=15
x=13
Hence, the dimensions of the rectangle are length=15 cm and width=13 cm
