my final two dimensions for the paintings were 48 by 72, I know the the new area is 4 times as large so my dimensions will also be 4 times as large as the original dimensions so I simply multiplied 12 by 4 and 18 by 4 to get my answer of 48 by 72.

First I multipled 18*4=which I got 72 for the first one and for the second one I multipled 12*4=which equals 48 . my first answer is 72 and my second answer is 48.

My answer is 48 by 72 cm because, you multiply 18 and 4=72, and 12 and 4=48 , because, it says 4 times . So its 72 by 48 cm.

My answer is 48 by 72 because the new area was 4 times the large dimensions so I multiply 4x12=48 then 18x4=78 so I found that the dimensions are 48 by 72.

Fist what I did is that I multiply 12×4 and I got 48 and a multiply 18×4 and I got 72 so then I just multiply 48×72 and I got 3,456 dimension so it was 72 cm and 48 cm.

i will add 12+18=30 and then i will divide 30 by 4 and the answer is 5 r10 that is my answer.

In order to get four times the area, I would need to double both dimensions. Since area is the length multiplied by the height, if I were to double both the length and the height by two then the overall area would increase 4 times. For example, if the dimensions of the picture frame were 1 cm by 2 cm then the area would be 2 square centimeters. If I were to double both dimensions resulting in 2 cm by 4 cm then the area would be 8 square centimeters. 8 is four times larger than two. Therefore, if a picture frame is 12 cm by 18 cm and you want the area to be four times larger then the new picture frame dimensions would be 24 cm by 26 cm.

I think the new dimensions are 48cm by 72cm because I just multiplied 12 and 18 by 4 Leave a Reply. |
