Question

The length of a rectangle of area 45m² is 9 cm. what is it's breadth?​

Answer 1

Answer:

Photosynthesis is the process in which green plants use sunlight to make their own food. Photosynthesis is necessary for life on Earth. ... Green plants use this light energy to change water and carbon dioxide into oxygen and nutrients called sugars.

Answer 2

Answer:

Let the breadth of the rectangle be x cm.

Then, the length of the rectangle is (x+9) cm.

So, area of rectangle = length x breadth =x(x+9)cm

2

Now, length of new rectangle =(x+9+3) cm =(x+12) cm and

breadth of new rectangle =(x+3) cm.

So, area of new rectangle = length × breadth =(x+12)(x+3)cm

2

According to the given condition,

(x+12)(x+3)=x(x+9)+84

⇒x

2

+12x+3x+36=x

2

+9x+84

⇒15x+36=9x+84

⇒15x−9x=84−36

⇒6x=48

⇒x=8

So, breadth of the rectangle is 8 cm and length

=8+9=17 cm.
