Perimeter of the Homemade Feeder

To find the lengths of all sides of the homemade feeder, let's assign variables to the lengths of the sides.

Let: - Side 1 = x cm - Side 2 = (x + 21) cm - Side 3 = (x/4) cm - Side 4 = (x + 14) cm

The perimeter of a quadrilateral is the sum of all its sides. In this case, the perimeter of the homemade feeder is given as 119 cm.

So, we can set up the equation:

x + (x + 21) + (x/4) + (x + 14) = 119

Now, let's solve for x to find the lengths of all sides.

To solve the equation, we can simplify it by combining like terms:

x + x + 21 + x/4 + x + 14 = 119

Combining the x terms:

4x + 84 + x/4 = 119

Multiplying through by 4 to eliminate the fraction:

16x + 336 + x = 476

Combining the x terms again:

17x + 336 = 476

Subtracting 336 from both sides:

17x = 140

Dividing both sides by 17:

x = 8.235

Now that we have the value of x, we can find the lengths of all sides:

- Side 1 = x = 8.235 cm - Side 2 = x + 21 = 8.235 + 21 = 29.235 cm - Side 3 = x/4 = 8.235/4 = 2.05875 cm - Side 4 = x + 14 = 8.235 + 14 = 22.235 cm

Therefore, the lengths of all sides of the homemade feeder are approximately: - Side 1: 8.235 cm - Side 2: 29.235 cm - Side 3: 2.05875 cm - Side 4: 22.235 cm

Please note that these values are approximate due to rounding.
