The perimeter of rectangular park is 450m.the length of the sides is in the ratio 3:2.find the area of the rectangle

matrenka [14]

Answer: 12,150 m²

<u>Step-by-step explanation:</u>

The ratio is 3:2 which means

Length (L) = 3x

Width (w) = 2x

Perimeter (P) = 2L + 2w

450 = 2(3x) + 2(2x)

450 = 6x + 4x

450 = 10x

45 = x

L = 3x w = 2x

= 3(45) = 2(45)

= 135 = 90

Area (A) = L × w

= 135 × 90

= 12,150

Solve for x b=1/6π n ^2 x

Setler [38]

Answer:

$\large\boxed{x=\dfrac{6b}{\pi n^2}}$

Step-by-step explanation:

$b=\dfrac{1}{6}\pi n^2x\qquad\text{multiply both sides by 6}\\\\6b=\pi n^2x\qquad\text{divide both sides by}\ \pi n^2\neq0\\\\\dfrac{6b}{\pi n^2}=b$

16. The weather report gives the temperature as 35 degrees Celsius. Find the

musickatia [10]

Answer:

$F=95\°$

Step-by-step explanation:

we know that

$C=\frac{5}{9}(F\°-32)$

In this problem we have

$C=35\°$

substitute the given value in the formula and solve for F

$35\°=\frac{5}{9}(F\°-32)$

$F-32=\frac{9}{5}(35)$

$F=\frac{9}{5}(35)+32$

$F=95\°$
