Question

perimeter of a room is 18 m it is 4 m wide find its length and area​

Answer 1

Answer:

solve using

perimeter of a rectangle = 2 ( length + breadth)

18 = x + 4

18-4= x

14 =x

hence, length = 24 m

now,

area

length × breadth

24 × 4 m

76 m

Answer 2

Answer:

The lenght = 5 m

The area =20 m

Step-by-step explanation:

The perimeter=18 m

                       =2(lenght+breath)

The width=     4 m

The lenght= AREA-b

                       2

                    = 18 -4 =5 m

                        2

 THEREFORE, The area=l*b

                                        =5*4

                                         =20 m
