Question

87. Find the breadth of the rectangle if the area of the rectangle is 45 m² and its length is 9m
​

Answer 1

Answer:

The given question is as follows:-

(1). If the perimeter of a rectangle is 45 cm and its length is 9 cm , then what is

the width ?

Solution:- we know that

(length+breadth) = perimeter of rectangle / 2.

or. 9 cm + breadth =45 cm/2

or. breadth = 22.5 cm - 9 cm

or breadth = 13.5 cm. Answer.

(Here breadth of a rectangle is greater than its length.)

OR

(2) If the area of a rectangle is 45 cm^2 and its length is 9 cm, then what is the

width ?

Solution:- we know that

Breadth of a rectangle= area of a rectangle/ length of rectangle.

= 45 cm^2/9 cm

= 5 cm. Answer.
