Step 1: find the area of the base
A=l*w = 8.25*5.5 = 45.375

Step 2: find the perimeter of the base 
P=2l+2w = 2(8.25) + 2(5.5) = 16.5 + 11 = 27.5

Step 3: find the surface area of the prism
SA=2A+Ph = 2(45.375) + 27.5(4.5) = 90.75 + 123.75 = 214.5


Hope this helps

As , we know Total surface area of Right rectangular prism or Cuboid is given by the formula -

2(lb+bh+hl)

where , l , b and h are length , Breadth and hieght respectively.

So, Total surface area of the given rectangular prism →

2{(8.25×5.5)+(5.5×4.5)+(4.5×8.25)}

= 2{45.375+24.75+37.125}

= 2{107.25}

= 214.5 cm²

Answer ) 214.5 cm² of gift wrap is needed.

P=2L+2W find the width of a rectangle whose length is 35 and perimeter is 82in
mart [117]

Answer:

6

Step-by-step explanation:

We can fill in what we know which is the length and perimeter.

82=2(35)+2(w)

Multiply 35 x 2 = 70

82-70= 12

12/2=6

The product of two rational numbers is 9⁄7 and one of them is 15⁄14. Then the other rational number is​
Rasek [7]

Answer:

The other rational number in the operation given is:

  • <u>6/5</u>

Step-by-step explanation:

To obtain the number in the operation given, we're gonna represent the operation:

  • r * 15/14 = 9/7

Where:

  • r = the other rational number.

Now we are going to solve r to identify its value in numbers:

  • r * 15/14 = 9/7
  • r = \frac{\frac{9}{7} }{\frac{15}{14}} (We pass a number that is multiplying to the left of the equal, to divide to the right of the equal symbol)
  • r = \frac{6}{5}

As you can see, when we operate, <u>the result is 6/5</u>, and we can prove this multiplying as we had in the original equation, replacing r by 6/5:

  • r * 15/14 = 9/7
  • 6/5 * 15/14 = 9/7
  • 9/7 = 9/7

In this form, we know the result is correct.

The distance around a rectangular cafe is 35m . The ratio of length of the cafe to the width is 3:2. Find the dimension of the
marusya05 [52]

Hi there! :)

Answer:

Length = 10.5 m, width = 7 m.

Step-by-step explanation:

Given:

Perimeter, or P = 35 m

Ratio of l to w = 3 : 2

Since the ratio is 3 : 2, let l = 3x, and w = 2x.

We know that the formula for the perimeter of a rectangle is P = 2l + 2w. Therefore:

35 = 2(3x) + 2(2x)

35 = 6x + 4x

35 = 10x

x = 3.5

Plug this value of "x" into each expression to solve for the dimensions:

2(3.5) = w

w = 7 m

3(3.5) = l

l = 10.5 m

Therefore, the dimensions are:

Length = 10.5 m, width = 7 m.
