Answer 1

АВ+ВС+ВС+АС+АВ+АС=18.5+15.8+17.7
2АВ+2ВС+2АС=52
АВ+ВС+АС=52:2
АВ+ВС+АС=26см

Answer 2

Problem Analysis

We are given the lengths of three sides of a triangle: AV, AS, and VS. We need to find the perimeter of the triangle.

Solution

To find the perimeter of the triangle, we need to add the lengths of all three sides.

Let's label the sides of the triangle as follows: - AV = a - AS = b - VS = c

The perimeter of the triangle (P) is given by the formula: P = a + b + c

We are given the values of a, b, and c, so we can substitute them into the formula to find the perimeter.

Calculation

Substituting the given values into the formula, we have: P = AV + AS + VS = a + b + c

From the given information, we have: AV + VS = 18.5 cm AS + VS = 15.8 cm AV + AS = 17.7 cm

We can solve these equations to find the values of a, b, and c.

Adding the first and third equations, we get: 2AV + 2VS = 36.2 cm

Subtracting the second equation from this result, we get: 2AV + 2VS - (AS + VS) = 36.2 cm - 15.8 cm 2AV + VS - AS = 20.4 cm

Substituting the values of AV + VS and AS from the given information, we have: 2(18.5 cm) + VS - 15.8 cm = 20.4 cm 37 cm + VS - 15.8 cm = 20.4 cm VS + 21.2 cm = 20.4 cm VS = -0.8 cm

This result indicates that there might be an error in the given information, as a side length cannot be negative. Please double-check the values provided for AV, AS, and VS.

If the values are correct, please provide additional information or clarify the problem statement so that we can assist you further.
