a carpet is place in a room 5m by 4m,leaving a margin of 50cm all around .find the cost of this carpet at shillings 63 persquare

assuming the cost is 63/m^2, it will come to

(5-2*.5)(4-2*.5)(63)

50÷100=05

5.5×4.5=24.75
5×4=20
24.75-20.00=4.75×63=299.25

To find the cost of the carpet, we first need to calculate the area of the room that needs to be covered by the carpet.

Given:
Length of the room = 5m
Width of the room = 4m
Margin all around = 50cm = 0.5m

To calculate the length and width of the carpet needed, we subtract the margin from the dimensions of the room:

Length of carpet = Length of room - (2 * Margin)
= 5m - (2 * 0.5m)
= 5m - 1m
= 4m

Width of carpet = Width of room - (2 * Margin)
= 4m - (2 * 0.5m)
= 4m - 1m
= 3m

Now, we calculate the area of the carpet:

Area of carpet = Length of carpet * Width of carpet
= 4m * 3m
= 12 square meters

Next, we need to calculate the cost of the carpet per square meter:

Cost per square meter = 63 shillings

Finally, we multiply the area of the carpet with the cost per square meter to get the total cost of the carpet:

Total cost of carpet = Area of carpet * Cost per square meter
= 12 square meters * 63 shillings
= 756 shillings

Therefore, the cost of the carpet is 756 shillings.
