Question

Найдите периметр треугольника большая сторона которого имеет длину 7 см а две другие 5 см каждая рассмотри выражения разбей их на группы так чтобы в каждой оказались похожие выражения запиши их в разные столбики и выполни вычисления

Answer 1

Периметр = 7+5+5 = 17 см

Answer 2

Calculating the Perimeter of a Triangle

To calculate the perimeter of a triangle with sides of lengths 7 cm, 5 cm, and 5 cm, we can use the formula:

Perimeter = Sum of all three sides

Let's break down the calculation into groups and perform the necessary computations.

Grouping the Expressions

We'll group the expressions as follows: - Expression 1: Sum of the three sides - Expression 2: Calculation of the perimeter

Performing the Calculations

1. Expression 1: - Sum of the three sides: 7 cm + 5 cm + 5 cm

2. Expression 2: - Perimeter = Sum of the three sides

Calculating the Perimeter

Now, let's perform the calculation: 1. Expression 1: - Sum of the three sides: 7 cm + 5 cm + 5 cm = 17 cm

2. Expression 2: - Perimeter = Sum of the three sides = 17 cm

So, the perimeter of the triangle is 17 cm.
