Step-by-step explanation:
let width be "w"
given,length of rectangle is 3 units greater than its width
length= w+ 3
perimeter of rectangle= 2( l+ b)
= 2[( w+3)+ w]
= 2(w to the power of 2 + 3w)
= 2w to the power of 2 + 6w
is the answer
The perimeter of the rectangle is 4w+6 units
The perimeter of a rectangle is the sum of its four sides. Perimeter of Rectangle = 2 (Length + Width) units.
According to the question
Width of rectangle = w
Length of rectangle = w+3
Perimeter of Rectangle = 2 (Length + Width)
= 2( w+3 +w)
= 2(2w+3)
= 4w+6 units
Hence, The perimeter of the rectangle is 4w+6 units .
