Question

The length of a rectangle is 12 m more than twice the width. The area of the rectangle is 320 spuare meter. Write an equation that can be used to find the lenght and width of the rectangle. Also find the dimension of the rectangle.​​

Answer 1

Answer:

Let the breadth of the rectangle is b cm.

So, the length of the rectangle is 2b cm.

We know that the perimeter of rectangle is

=2(l+b)

Since, perimeter of rectangle is 120 cm. 

Therefore,

6b=120

b=20 cm

And l=40 cm

So, the area of rectangle is

=20×40=800 cm2

Hence, the length is 40 cm, breadth is 20 cm and area is 800 cm2

Answer 2

Step-by-step explanation:

The length of a rectangle is 12 m

more than twice the width.

The area of the rectangle is 320 spuare meter.

Write an equation that can be used to find the lenght and width of the rectangle.

Also find the dimension of the rectangle.
