The length and width of a rectangle or both doubled what is the ratio of the area of the larger rectangle to the area of the smaller rectangle

ratio of the area of the larger rectangle to the area of the smaller rectangle is 4:1 .

Step-by-step explanation:

Here we have ,The length and width of a rectangle or both doubled  . We need to find that  the ratio of the area of the larger rectangle to the area of the smaller rectangle . Let's solve this:

Area of smaller rectangle:

Let length and breadth are x & y respectively

⇒

⇒

Area of larger rectangle:

Let length and breadth are 2x & 2y( according to question sides are doubled) respectively ,

⇒

⇒

⇒

⇒

⇒

Therefore , ratio of the area of the larger rectangle to the area of the smaller rectangle is 4:1 .
