Question

(1) Find the length and perimeter of a rectangle of area 900 mº2 and breadth 20 m.​

Answer 1

Step-by-step explanation:

Given:-

Breadth of the rectangle = 20m

Area of the rectangle = 900m^2

To find:-

Length of the rectangle

Perimeter of the rectangle

Solution:-

As we know,

Area of a rectangle = Length * Breadth

900 m^2 = Length * 20 m

=> 900m^2/20m = Length

=> 45m = Length

Now,

Perimeter of a rectangle = 2(Length +Breadth)

= 2(45m + 20m)

= 2(65m)

= 130 m

Answer 2

Answer:

length = area / breadth = 900/ 20

length = area / breadth = 900 / 20 = 45 ans
