Question

Чему равна площадь незакрашенной части пряомугольника,если длина одной клетки равна 1 см? Незакрашенно 28 клеток.Заранее спасибо И перевидите в квадратные метры

Answer 1

Вычислим площадь одной клетки
S=a*a
S=1*1=1 (кв см)

Вычислим площадь 28 клеток
1*28=28 (кв см)

Переведем в кв метры
1 кв м=10000 кв см
28 кв см=28:10000=0,0028 кв м

Answer 2

Calculating the Area of the Unshaded Rectangle

To calculate the area of the unshaded part of the rectangle, we can use the given information that the length of one cell is 1 cm and there are 28 unshaded cells.

The area of the unshaded part can be calculated by multiplying the length and width of the unshaded part.

Length of the Unshaded Part: - Given that the length of one cell is 1 cm, the length of the unshaded part is 28 cm.

Width of the Unshaded Part: - The width of the unshaded part is not provided, so we'll assume it to be 1 cm for the purpose of this calculation.

Calculating the Area: - The area of the unshaded part = Length * Width - Area = 28 cm * 1 cm - Area = 28 cm²

Converting to Square Meters

To convert the area from square centimeters to square meters, we can use the conversion factor: 1 square meter = 10,000 square centimeters

Converting to Square Meters: - Area in square meters = 28 cm² / 10,000 - Area in square meters = 0.0028 m²

So, the area of the unshaded part of the rectangle is 28 cm², which is equivalent to 0.0028 square meters.
