Question

На листе бумаги изображены прямоугольник и квадрат с равными периметрами. Ширина прямоугольника 3 см, и она на 1 дм меньше длины. Найдите площади прямоугольника и квадрата. Помогите пожалуйста, срочно надо!

Answer 1

В 1 дм 10 см получается 3 плюс 10 это 13 получается з умножить на 13 это площадь тоесть 39

Answer 2

Problem Analysis

We are given a rectangle and a square with equal perimeters. The width of the rectangle is 3 cm, and it is 1 dm (10 cm) shorter than its length. We need to find the areas of the rectangle and the square.

Solution

Let's assume the length of the rectangle is L cm. According to the given information, the width of the rectangle is 3 cm, and it is 1 dm (10 cm) shorter than its length. Therefore, the width of the rectangle can be expressed as (L - 10) cm.

The perimeter of a rectangle is given by the formula: P = 2(L + W), where P is the perimeter, L is the length, and W is the width.

Since the rectangle and the square have equal perimeters, we can set up the following equation:

2(L + (L - 10)) = 4L

Simplifying the equation:

2L + 2L - 20 = 4L

4L - 4L = 20

0 = 20

This equation has no solution, which means there is no valid solution for the given conditions. It seems there might be an error in the problem statement or the given information.

Without further information or clarification, it is not possible to find the areas of the rectangle and the square.
