Question

найдите периметр прямоугольника ABCD если биссектриса угла A делит стороны BC на отрезки 45,6см и 7,85см

Answer 1

Биссектриса отсекает равнобедренный треугольник АВК и его стороны равны 45,6.

А значит АВ = 45,6

ВС=45,6+7,85=53,45

Р=2АВ+2ВС=2*45,6+2*53,45=91,2+106,9=198,1

Ответ: 198,1

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Answer 2

Perimeter of Rectangle ABCD

To find the perimeter of rectangle ABCD, we need to know the lengths of all four sides of the rectangle. Given that the angle bisector of angle A divides side BC into segments measuring 45.6 cm and 7.85 cm, we can determine the lengths of the other sides.

Let's denote the lengths of the sides as follows: - Side AB = a - Side BC = b - Side CD = c - Side DA = d

According to the information provided, the angle bisector of angle A divides side BC into segments measuring 45.6 cm and 7.85 cm. Therefore, we can conclude that: - Side BC = 45.6 cm + 7.85 cm = 53.45 cm

To find the perimeter of the rectangle, we can use the formula: Perimeter (P) = a + b + c + d

However, we still need to determine the lengths of sides AB, CD, and DA. Unfortunately, the given information does not provide direct information about these sides. Therefore, without additional information, we cannot determine the exact perimeter of rectangle ABCD.
