Arella needs to paint a board that is 2 meters wide and 3 meters tall. If one cup of paint will cover 1000 square centimeters, h
scZoUnD [109]

Hey!


The area of the board is 60,000 centimeters.


1 meter = 100 centimeters

2 meters = 200 centimeters

3 meters = 300 centimeters


Area = length × width

300 × 200 = 60,000


One cup covers 1,000 centimeters. To cover 60,000 centimeters, divide 60,000 by 1,000.


60,000 \div 1,000 = 60


That means Arella needs 60 cups

rewona [7]

Answer:

B. 36 C. 180 D. 240 E. 1,656

Step-by-step explanation:

Partial product is the multiplication of individual digit of a number in turn with each digit of the others where each digit maintains its place.

Using distributive property to multiply 24 × 69 to determine our partial products:

i.e.

24 × 69 = 24 × (60 + 9)

= (24 × 60) + (24 × 9)

= 60 (20 + 4) + 9(20 + 4)

So; we can have:

= (60 × 20) + (60 × 4) + (9 × 20) + (9 × 4)

= 1200 + 240 + 180 + 36  

= 1656
