A rectangular field with perimeter of 80m is to have an area of at least 380m² . Describe the possible lengths and of the field.

Kryger [21]

$let \: x \: be \: the \: length \\ let \: y \: be \: the \: width$

$perimeter = 2x + 2y \\ area = xy$

$2x + 2y = 80 \\ xy = 380 \\ \\ x + y = 40 \\ xy = 380 \\ \\ x = 40 - y \\ (40 - y)y = 380$

$40y - y {}^{2} = 380 \\ y {}^{2} - 40y + 380 = 0 \\ y {}^{2} - 40y + 400 = 20 \\ (y - 20) {}^{2} = 20 \\ y - 20 =± \sqrt{20} \\ y_{1}=20-√20≈15.52786\\ y_{2}=20+√20≈24.4721$

Answer:

The number of kids NOT wearing socks in the gym = 20

Step-by-step explanation:

Here, the total number of kids in the gym = 80

Now, 75% of the kids are wearing socks.

Let us assume the number of kids wearing socks = m

⇒ 75 % of 80 = m

Calculating the value of m ,we get:

$\frac{75}{100} \times 80 = m\\\implies m = 60$

⇒ 60 kids are wearing socks.

Kids not wearing socks = Total kids in gym - Kids wearing socks

= 80 - 60 = 20

Hence, the number of kids NOT wearing socks in the gym = 60.
