The perimeter of the triangle BMP is 128 mm It is known that the side BM is 5 cm 6 mm MP is 2 times

The perimeter of the triangle BMP is 128 mm It is known that the side BM is 5 cm 6 mm MP is 2 times shorter than the BM. Determine the length of the side BP.

First of all, we calculate the unknown lengths of the sides of the triangle.

Let us find the length of the side of the MR, if, according to the condition, it is 2 times shorter than the side of the VM, the length of which is 5 cm 6 mm (or 56 mm):

56: 2 = 28 (mm).

The perimeter of a triangle is equal to the sum of its three sides.

So we now calculate the unknown side of the triangle BP, subtracting from the perimeter of the triangle BMP the sum of the two known sides MP and BM:

128 – (56 + 28) = 128 – 84 = 44 (mm).

Answer: The length of the BP side is 44 mm.
