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

Answer 1

Answer:

12 cm and 54 cm

Step-by-step explanation:

A=180 cm2

l=15cm

we have

A=lb

180=15b

b=180/15

b=12cm..........

p=2(l+b)

=2(15+12)

=2*27

54

Answer 2

Answer:

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
