The mural of your school mascot is 4 feet by 12 feet and is to be completely framed using a single row of square tiles each 2 inches on an edge. If the tiles are 0.10 each, find the cost, in dollars, of the tiles needed to frame the mural.
+204 The school mascot is rectangular in nature.
Perimeter P = 2(L+W)
L is the length = 4feet
W is the width = 12 feet
Perimeter = 2(4+12)
Perimeter = 2(16)
Perimeter = 32 feet
Convert to inches
12 in = 1feet
x = 32 feet
Cross multiply
x = 12 * 32
x = 384in
Hence the perimeter of the school mascot is 384 in
If it is to be completely framed using a single row of square tiles each 2 inches on an edge
2 inches = 1 tiles
384 inches = y tiles
Cross multiply
2y = 384
y = 384/2
y = 192 tiles
The number of tiles needed is 192 tiles
Get the cost of 192tiles
If the tiles are $010 each. 192 tiles will cost 192 * 0.1 = $19.2
Hence the cost of the tiles needed is $19.2
