Question

Скатерть-самобранка размером 165 на 165 см долго провалялась в чулане у Бабы-яги со старым тряпьём .Мыши испортили 2/3 части всей скатерти,1/5 часть проела моль .Чему равна площадь уцелевшей части скатерти?

Answer 1

165*165=27225см в квадрате-это S самой скатерти27225*2/3=18150 см в квадрате проели мыши 
27225*1/5=5445 см2 проела моль 
27225-18150-5445=3630

Answer 2

Calculating the Area of the Surviving Part of the Tablecloth

To calculate the area of the surviving part of the tablecloth, we can follow these steps:

1. Calculate the Total Area of the Tablecloth: - The tablecloth is 165 cm by 165 cm in size. - The total area of the tablecloth can be calculated using the formula: Area = length × width.

2. Determine the Area Damaged by Mice and Moths: - 2/3 of the tablecloth was damaged by mice. - 1/5 of the tablecloth was eaten by moths.

3. Calculate the Area of the Surviving Part: - Subtract the damaged areas from the total area to find the area of the surviving part.

Let's calculate the area of the surviving part of the tablecloth using the provided information.

Calculation

1. Total Area of the Tablecloth: - Area = 165 cm × 165 cm = 27,225 square cm.

2. Area Damaged by Mice: - 2/3 of the tablecloth was damaged by mice. - Area damaged by mice = (2/3) × 27,225 square cm.

3. Area Eaten by Moths: - 1/5 of the tablecloth was eaten by moths. - Area eaten by moths = (1/5) × 27,225 square cm.

4. Area of the Surviving Part: - Area of the surviving part = Total area - (Area damaged by mice + Area eaten by moths).

Result

The area of the surviving part of the tablecloth can be calculated using the above steps.
