A carpet is placed in a room 5m by 4m,leaving a margin of 50 all around .find the cost of this carpet at sh 63 persquare
It would help if you proofread your questions before you posted them. Need to know units.
50 what?
"63 persquare" what?
To find the cost of the carpet, we need to calculate the area covered by the carpet.
First, we need to find the dimensions of the actual carpeted area. We know that there is a margin of 50 on all sides, so we need to subtract this margin from both the length and width of the room.
The length of the actual carpeted area will be 5m - 2*50cm = 5m - 1m = 4m. (Since there are two margins, one on each side, we multiply 50 by 2).
The width of the actual carpeted area will be 4m - 2*50cm = 4m - 1m = 3m.
Now that we have the dimensions of the carpeted area, we can calculate the area by multiplying the length by the width: 4m * 3m = 12 square meters.
The cost of the carpet is given as sh 63 per square meter, so to find the total cost, we need to multiply the area by the cost per square meter:
12 square meters * sh 63/square meter = sh 756.
Therefore, the cost of the carpet is sh 756.
