Answer:

$490.9\ ft^{2}$

Step-by-step explanation:

we know that

The total area is equal to

$A=10(h)+2\pi r(h)+10(h)$

we have

$h=9\ ft$

$r=5.5\ ft$

$\pi=3.14$

substitute

$A=10(9)+2(3.14)(5.5)(9)+10(9)$

$A=490.9\ ft^{2}$

A rectangular room is 3 3 times as long as it is wide, and its perimeter is 64 64 meters. find the dimension of the room.

lora16 [44]

Perimeter = 2L + 2W (where L = length and W = width)

And we are given that L = 3W

So substituting for L, we have the equation:-

2(3W) + 2W = 64

6W + 2W = 64

8W = 64

W = 8 meters

So the length = 3*8 = 24 meters

Answer:- Length = 24 m and Width = 8 m.
