Question

(b) The area of a rectangle is 180 cm2 and its length is 15 cm. Find its breadth
and perimeter.​

Answer 1

Answer:

 

• 54 cm

Step-by-step explanation:

breadth = 12 cm   perimeter = 54 cm

Step-by-step explanation:

Area of rectangle = length × breadth

                      180  = 15 × breadth

                breadth = 180÷15

                breadth =  12 cm

Perimeter of rectangle = 2 ( l + b)

                                    =  2 ( 15 + 12 )

                                    =  2 ( 27 )

                                    =  54 cm

Answer 2

Step-by-step explanation:

area = length * breadth

180 = 15 * breadth

180/15 = breadth

12 = breadth

Perimeter = 2( length+breadth )

= 2( 15+12)

= 54 cm
