Johnson's house was $112.00 per square meter to build. The house is 12 meters wide and 18 meters long. How much did it cost to build the house?
12x18=216
$112x216=24,192
or
$112x12=1,344
$112x18=2,016
Add=$3,360 to build the house??
One of those is right. Which answer makes the most sense to you?
Hint: Which of your answers finds the number of square meters in the house?
I am in 3rd grade, we are not multiplying by 3 digits that is why i tried the second one. I think it is the 2nd one. after adding both answers??
This is not part of any third grade math curriculum I know!
Your first answer is correct.
Thank you Ms. Sue.
I am Bella's Father, I also found it strange that they would post this type of a question for my 8 year old.
Quick question does this one sound right for her grade. I tried to help her solve it, but my Daughter seemed confused.
A rectangular room is 20 meters by 25 meters. It would cost $20.00 per square meter to paint a room. How much would it cost to paint the room?
Answer?:
20x25=500
$20x500=$10,000 to pain the room
or
20x$20=$400
25x$20=$500
=$900 to paint the room
Thank You Ms. Sue I greatly appreciate it,
I will need to bring this up to her teacher.
The last question makes no sense. First, the room's dimensions in feet would be 60 by 75. That's the size of a very large house.
When we paint a room, we usually paint the walls of the room, but the problem doesn't state the height of the walls.
Yes, please check with her teacher.
Thank you very much Ms. Sue I greatly appreciate your help. I am glad I came across this site, I will visit it frequently.
It will defiantly help my Daughter and myself to further assist her with these math problems.
To find the cost of building the house, we need to multiply the cost per square meter by the area of the house. First, calculate the area of the house by multiplying the width (12 meters) by the length (18 meters):
Area = Width x Length = 12 meters x 18 meters = 216 square meters.
Next, multiply the area of the house by the cost per square meter to determine the total cost of building the house:
Total Cost = Area x Cost per square meter = 216 square meters x $112 per square meter = $24,192.
Therefore, it would cost $24,192 to build the house.
