Answer:

Area = $3617.28 \ ft^2$

Step-by-step explanation:

Radius of bi circle = 12 + 24 = 36

Radius of small circle = 12

Area of shaded region = area of big circle - area of small circle

$= \pi \times 36^2 - \pi \times 12^2\\\\= \pi \times (36^2 - 12^2)\\\\ = \pi \times 1152\\\\= 3617.28 \ ft^2$

The length of a rectangle is three times its width. if the area of the rectangle is 300 yd2 , find its perimeter.

Svetradugi [14.3K]

Let, width = x
Length = 3x

It is given that, 3x * x = 300
3x² = 300
x² = 300 / 3
x = √100
x = 10
& 3x = 3(10) = 30

Perimeter = 2(l + w)
P = 2(10 + 30)
P = 2(40) = 80

In short, Your Answer would be 80 Yards

Hope this helps!
