Question

A rectangle has its length 3 times the width. If it is 3cm shorter and 3cm wider it becomes a square. What is the length of the square?

Answer 1

Answer:

Step-by-step explanation:

Let width of the rectangle is x

and length be 3x

then the width of square will be x+3

and the length be 3x-3

sides of square are equal therefore

x+3=3x-3

2x=6

x=3=length of a side

then perimeter of square will  be 4×3=12

Answer 2

Breadth be x
Length =3x

x+3=3x-3
2x=6
X=3cm=breadth

Length =3x=9 cm
