Question

У ани есть кусок серого меха прямоугольной формы длиной 80 см и шириной 30 см.для изготовления мягкой игрушки ей понадобится одна шестая часть куска меха.найдите площадь оставшейся части

Answer 1

80×30=2400 (см)-площадьмеха
2400÷6=400 (см)-одна шестая часть меха

Answer 2

S куска = 80см * 30см = 240см
одна шестая часть куска = 240см : 6 = 40см
S оставшейся части = 240см - 40см = 200см
Ответ: 200 см

Answer 3

Calculation of the Remaining Area of the Fur Piece

To find the area of the remaining piece of fur, we need to calculate the area of the original piece and then subtract the area used for making the soft toy.

The original piece of fur has a rectangular shape with a length of 80 cm and a width of 30 cm.

Area of the original piece of fur: To find the area of a rectangle, we multiply its length by its width. Area = length * width = 80 cm * 30 cm = 2400 square cm

The soft toy requires one-sixth of the original piece of fur. To find the area used for making the soft toy, we divide the area of the original piece by 6.

Area used for making the soft toy: Area used = Area of the original piece / 6 = 2400 square cm / 6 = 400 square cm

To find the area of the remaining piece of fur, we subtract the area used for making the soft toy from the area of the original piece.

Area of the remaining piece of fur: Area remaining = Area of the original piece - Area used for making the soft toy = 2400 square cm - 400 square cm = 2000 square cm

Therefore, the area of the remaining piece of fur is 2000 square cm.
