Question

СРОЧНО Прямоугольный дачный участок имеет площадь 81 а, его длина 90 м. Вычисли периметр участка. Ответ запиши в метрах. СРОЧНО

Answer 1

Ответ:

81а=8100м^2

90*x=8100 (т.к.S=a*b)

x=8100/90

x=90

90 метров- вторая сторона

Р=2(а+b)

P=2(90+90)=360м

Ответ:360м

Answer 2

Calculation of Perimeter

To calculate the perimeter of a rectangular plot, we need to know the length and width of the plot. In this case, we are given that the length of the plot is 90 meters. However, the width of the plot is not provided. Without the width, it is not possible to calculate the perimeter accurately.

Please provide the width of the rectangular plot so that I can calculate the perimeter for you.
