Question

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

Answer 1

58+15=73мм мп

53-23=50мм пк

58+73+50=181

Answer 2

Perimeter of Triangle KMR

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

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

Let's calculate the lengths of sides MR and RK:

- Side MR = Length of side KM + 1 cm 5 mm = 5 cm 8 mm + 1 cm 5 mm = 6 cm 13 mm- Side RK = Length of side KM - 2 cm 3 mm = 5 cm 8 mm - 2 cm 3 mm = 3 cm 5 mm Now, we can calculate the perimeter of triangle KMR by adding up the lengths of all three sides:

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

Perimeter = 5 cm 8 mm + 6 cm 13 mm + 3 cm 5 mm

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

- Length of side KM = 5 cm 8 mm = 508 mm - Length of side MR = 6 cm 13 mm = 613 mm - Length of side RK = 3 cm 5 mm = 305 mm

Now, we can calculate the perimeter:

Perimeter = 508 mm + 613 mm + 305 mm = 1426 mm

Therefore, the perimeter of triangle KMR is 1426 mm.
