Required probability = (1/2)^5 = 1/32
Its c (assuming that its a fair coin).
A. Let
L = length of a rectangular soccer field
W = width of a rectangular soccer field
P = perimeter of a rectangular soccer field
L = W + 50 (the length is longer than the width)
For the equation, the formula for a perimeter of the rectangle is
2L + 2W = P
Since the length and perimeter are given, substitute them as
2(W + 50) + 2W = 340
b. Solving for W,
2(W + 50) + 2W = 340
2W + 100 + 2W = 340
2W + 2W = 340 - 100
4W = 240
(4W)/4 = 240/4
W = 60 yards
Solving for L,
L = 60 + 50 = 110 yards
The rectangular soccer field has the length of 110 yards and the width of 60 yards.
