In a rectangle, the point of intersection of the diagonals is 4 cm farther from the smaller side than from the larger side. The square corner is 56cm. Find its sides
Let the length of the segment OM = X cm, then, by condition, the length of the segment OK = (X + 4) cm.
In a rectangle, the diagonals are equal and are halved at the intersection. ОВ = DO = ВD / 2.
The OAD triangle is isosceles, then OM is the height and median of the triangle. AM = DM, then OM is the middle line of the triangle ABD, and AB = 2 * OM.
Similarly, AD = 2 * OK.
The perimeter of the rectangle is: Ravsd = 2 * (AB + AD) = 2 * (2 * OM + 2 * OK) = 4 * (X + X + 4) = 56.
8 * X = 56 – 16 = 40.
X = OM = 40/8 = 5 cm.
OK = 4 + 5 = 9 cm.
Then AB = 2 * OM = 2 * 5 = 10 cm, AD = 2 * OK = 2 * 9 = 18 cm.
Answer: The sides of the rectangle are 10 cm and 18 cm.
