The perimeter of the rectangle is 56cm. The length of one of its sides is 5/14 of the perimeter and 15/8 of the length of 2 sides. find in the sides of the triangle.
Determine the value of the length of the first side of the triangle.
Multiply the known perimeter by 5/14.
56 * 5/14 = 4 * 5 = 20 cm.
Find the length of the second side of the figure.
To do this, we divide 20 centimeters by 15/8 part.
20/15/8 = 20 * 8/15 = 160/15 = 10 2/3 cm.
Find the total length of 1 and 2 sides of the triangle.
20 + 10 2/3 = 30 2/3 cm.
To find out the third side of the triangle, we subtract the found sum of the sides from the perimeter of the figure.
56 – 30 2/3 = 25 1/3 cm.
Answer: The length of the third side is 25 1/3 cm.
