By definition the area of a rectangle is:
 A = w * l
 The perimeter is:
 P = 2w + 2l
 Where,
 w: width
 l: long
 Substituting values:
 300 = w * l
 80 = 2w + 2l
 Solving the system of equations we have:
 l = 30 m
 w = 10 m
 Answer:
 
The length and width of the field are:
 
l = 30 m
 
w = 10 m

What is the value of x?
solniwko [45]

Answer:

x = 7.5

Step-by-step explanation:

Since we see that sides AD and DC are equal, as well as sides BE and EC, we can use this information to conclude that the value of 2x-7 is equal to double the value of DE.

2x - 7 = 4(2)

2x - 7 = 8

2x - 7 + 7 = 8 + 7

2x = 15

x = 7.5
