Question

Найдите периметр треугольника КМР если длина стороны КМ равна 5 см 8мм сторона МР на 1см5мм длиннее стороны КМ но короче на 2см 3мм стороны РК.

Answer 1

КМ=5.8
МР=5.8+1.5=7.3
РК=7.3+2.3=9.6
Р=5.8+7.3+9.6=22.7

Answer 2

МР=5см 8мм+ 1см5мм =7см 3ммРК=7см 3мм+2см 3 мм=9см 6ммР=КМ+МР+РК=5см 8мм+7см 3мм+9см 6мм=22СМ 7ММ

Answer 3

Perimeter of Triangle KMR

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

Given: - Length of side KM = 5 cm 8 mm - Length of side MR = 1 cm 5 mm longer than KM, but 2 cm 3 mm shorter than RK - Length of side RK

Let's calculate the lengths of the sides first:

1. Length of side KM = 5 cm 8 mm

2. Length of side MR = Length of side KM + 1 cm 5 mm - 1 cm 5 mm = 1 cm + 5 mm = 10 mm + 5 mm = 15 mm

3. Length of side RK = Length of side MR + 2 cm 3 mm - 2 cm 3 mm = 2 cm + 3 mm = 20 mm + 3 mm = 23 mm

Now, let's calculate the perimeter by adding up the lengths of all three sides:

Perimeter = Length of side KM + Length of side MR + Length of side RK

Substituting the values we calculated:

Perimeter = 5 cm 8 mm + 15 mm + 23 mm

To add these lengths, we need to convert them to a consistent unit. Let's convert everything to millimeters:

- 5 cm = 50 mm (1 cm = 10 mm) - 8 mm - 15 mm - 23 mm

Now we can add them up:

Perimeter = 50 mm + 8 mm + 15 mm + 23 mm

Calculating the sum:

Perimeter = 96 mm

Therefore, the perimeter of triangle KMR is 96 mm.
