Question

Найдите периметр прямоугольника одна сторона 5 3/4 дм а другая длинна на 1/2 метра

Answer 1

A = 5 m
b = a +  m
P = a + b =  (5) + (5 + ) = 5.75 + 6.25 = 12 m

Answer 2

Calculating the Perimeter of a Rectangle

To find the perimeter of a rectangle, you can use the formula:

Perimeter (P) = 2 * (length + width)

Given: - One side of the rectangle is 5 3/4 dm - The other side is 1/2 meter

Using the formula, we can calculate the perimeter as follows:

P = 2 * (5 3/4 + 1/2)

Calculation

P = 2 * (5 3/4 + 1/2) P = 2 * (23/4 + 1/2) P = 2 * (23/4 + 2/4) P = 2 * (25/4) P = 50/4 P = 12 1/2 dm

So, the perimeter of the rectangle is 12 1/2 dm
