Question

Jennies decided to replace the rectangular rug in her living room. the dimensions of the old rug are 8 feet by 4 feet. if the length and width of the new rug are twice the length and width of the old rug, the area of the new rug is how many times larger than the area of the old rug?
f) 1
g) 2
h) 3
j) 4
k) 5

Answer 1

Your answer is J) 4.

We can find this by first finding the area of the old rug by multiplying 8 by 4, which gives us 32 ft².

Then we find the dimensions of the new rug by doubling 8 and 4, to give us 16 and 8, and we can then multiply these to find the area of the new rug which is 128.

Finally, we divide 128 by 32 to find the scale it was multiplied by, and we get 4.

I hope this helps!
