Question

2. The area of a rectangle whose length and breadth are 9y and 4y² respectively is *​

Answer 1

Area of rectangle is lxb
Given,
Length=9y
Breadth=4y^2
=9yx4y^2
=36y^3

Answer 2

Given :

Length of the rectangle = 9y

Breadth of the rectangle = 4y

To Find :

Find the area of the rectangle ?

Solution :

We know that,

➣ Length of Rectangle = Length × Breadth

According to the question :

Length of Rectangle = Length × Breadth

➣ Area of Rectangle = 9y × 4y

➣ Area of Rectangle = 9 + 4 + y × y

➣ Area of Rectangle = 36 + y × y

➣ Area of Rectangle = 36 + y²

➣ Area of Rectangle = 36y²

Hence,

The Area of the Rectangle is 36y².
