8 and 12 please help im stuck on this one can someone help
24and 16
Really its such a easy prob 24 and 16 lol
I Tried Both Of Ur Answers And They Where Wrong! I Did This Prob In School And Got A 0 On My Math Test Because U Guys Lied. Now I Have To Stay For Office Hours :(
hejf
wow people have so much hard time on this well that's why my math is a A and I'm om the honor roll.
Pls help me with 3
To solve this problem, we need to find all possible ways to divide the 5x8 rectangle into smaller rectangles and calculate their areas.
One way to approach this is to try dividing the rectangle into rows and columns of equal lengths. For example, we can divide it into 5 rows and 1 column, giving us 5 smaller rectangles, each with an area of 8 square units. Alternatively, we can divide it into 1 row and 8 columns, resulting in 8 smaller rectangles, each with an area of 5 square units.
So, two possible area totals for the smaller rectangles are:
- 5 smaller rectangles, each with an area of 8 units: 5 x 8 = 40.
- 8 smaller rectangles, each with an area of 5 units: 8 x 5 = 40.
Now we can compare these possible area totals with the choices given:
A. 24 and 16:
- Neither 24 nor 16 is the possible area total we calculated.
B. 22 and 16:
- Neither 22 nor 16 is the possible area total we calculated.
C. 36 and 12:
- Neither 36 nor 12 is the possible area total we calculated.
D. 8 and 12:
- 8 is one of the possible area totals we calculated, but 12 is not.
Therefore, none of the given choices match the two possible area totals for the smaller rectangles, which are 40.
really? 5x8=40
Your area 36+12 = 48
