MissTica

Answer:

45 yards and 176 yards

Step-by-step explanation:

Perimeter of a rectangular playing field = 2(Length + width)

P = 2(L+W)..................... Equation 1

From the question,

Let the width of the rectangular playing field = x yards,

The the Length = 4x-4 yards.

Given: P = 442 yards.

Substitute these values into equation 1

442 = 2(4x-4+x)

442/2 = 5x-4

221 = 5x-4

5x = 221+4

5x = 225

x = 225/5

x = 45 yards.

Width = 45 yards.

Length = (45×4)-4 yards = 176 yards

Hence the dimensions of the playing field are, 45 yards and 176 yards

Ede4ka [16]

Answer:

Hey,

so if she works for seven hours at <em><u>both</u></em> jobs then we multiply how much she gets paid per hour times seven or 22.22*7=<em><u>155.54</u></em> and 13.55*7=<em><u>94.85</u></em>. Then we add what is underlined, 155.54+94.85= our answer which is <em><u>250.39</u></em> per day.
