Question

rectangular room of size 5 m × 35 DM is to be carpeted with carpet 7 DM wide. find length of carpet required​

Answer 1

Answer:

 The length of the carpet will be 250 DM.

Step-by-step explanation:

Given:  

     Length of room = 5m (1m =10 DM, So here 1m = 50 DM)

     Width of room   =  35 DM

     Width of carpet  =   7 DM

Solution:

FIrstly we will calculate the area of the room:

                Formula = Length * Width

Put the given value in the formula:

                 Area of the room will be = 50*35 = 1750 DM

Carpet's area will be equal to = Room's Area (Aa per question)

Put the given value in the above statement we will get

                   1750 DM (Room' area) = 7 DM*Length(* this is a sign of multiplication)

                   Length = 1750 DM\7 DM

                   Length = 250 DM     Answer
