It is 5%
It is: 20/400 times 100 = 5%
It is: 14 square m
First, convert the dimensions of the sheet from meters to centimeters: a 2m by 4m sheet is 200cm by 400cm. The area of the sheet is 200cm x 400cm = 80,000 cm². The area of one street sign, which is 20cm high and 80cm wide, is 20cm x 80cm = 1,600 cm². Therefore, the number of street signs that can be made is 80,000 cm² ÷ 1,600 cm² = 50 signs.

20cmx 20cm x20cm
The area of 4m by 4m is 16 square meters.
4m = 13.12 feet
-4m + 3 = -8 -4m = -8 -3 -4m = -11 4m = 11 m = 2.75
It is 40,000mm
V = 64 m3
It is 400cm or 4 meters
