Question

Древнеримские карты сворачивались в рулоны свитки чтобы имя было удобнее пользоваться в пути ширина такой карты в 4 раза меньше ее длины. Найди периметр и площадь карты, если её длинна 2м.

Answer 1

1) 2м:4=0,5(м) ширина карты
2) вычисляем периметр, это сумма длин сторон: (2+0,5)х2=5 (м)
3) площадь получаем, умножив длину на ширину: 2х0,5=1 (м ²)

Answer 2

Длинна = 2:4=0,5(м)
P=2+2+0,5+0,5=5(m)
S=2*0,5=1(m)

Answer 3

Ancient Roman Maps

Ancient Roman maps were often rolled into scrolls for convenient use while traveling. The width of these maps was four times smaller than their length. Let's calculate the perimeter and area of a map with a length of 2 meters.

To find the perimeter of the map, we need to add up the lengths of all four sides. Since the width is four times smaller than the length, we can calculate the width as 2 meters divided by 4, which equals 0.5 meters.

The perimeter of a rectangle is calculated by adding up the lengths of all four sides. In this case, the length is 2 meters and the width is 0.5 meters. Therefore, the perimeter can be calculated as follows:

Perimeter = 2 * (Length + Width) Perimeter = 2 * (2 + 0.5) Perimeter = 2 * 2.5 Perimeter = 5 meters

So, the perimeter of the map is 5 meters.

To find the area of the map, we multiply the length by the width. In this case, the length is 2 meters and the width is 0.5 meters. Therefore, the area can be calculated as follows:

Area = Length * Width Area = 2 * 0.5 Area = 1 square meter

So, the area of the map is 1 square meter.
