Answer:

Difference in their measurement will be 245532 mm

Step-by-step explanation:

We have given that Priya measured the perimeter of the desk and found the perimeter as 248 m

We know that 1m =1000mm

So 248 m = 248000 m

And Noah measured the perimeter of the same desk and found as 2468 m  

We have to find the difference in their measurement

Difference will be = 248000 - 2468  = 245532 mm

Answer: 2.70\ quarts\approx3\ quarts

Step-by-step explanation:

The area of a rectangle can be calculated with this formula:

A_r=lw

Where "l" is the lenght and "w" is the width.

And the area of triangle can be found with this formula:

A_t=\frac{bh}{2}

Where "b" is the base and "h" is the height.

First:

- Convert inches to feet:

(30\ in)(\frac{1\ ft}{12\ in})=2.5\ ft

- Convert the mixed number to decimal number:

30\frac{1}{10}=30+0.1=30.1

You can identify that the ramp is formed by three rectangles and two equal right triangles.

Since the bottom of the ramp does not have to be stained, you need to find:

1. The area of the smaller rectangle:

A_1=(2.5\ ft)(6\ ft)=15\ ft^2

2. The area of the larger rectangle on the top:

A_2=(30.1\ ft)(6\ ft)=180.6\ ft^2

3. The area of the triangles:

A_3=A_4=\frac{(30\ ft)(2.5\ ft)}{2}=37.5\ ft^2

Add the areas:

Total=15\ ft^2+180.6\ ft^2+37.5\ ft^2+37.5\ ft^2=270.6\ ft^2

Since a quart of stain covers 100 ft^2, for 270.6\ ft^2 you need to buy:

\frac{270.6}{100}=2.70\ quarts\approx3\ quarts
