Answer:
6 ft
Step-by-step explanation:
The rectangles are similar, so their corresponding sides will be proportionate.
The proportion of their sides will be:
length of smaller/width of smaller=length of larger/width of larger
We know the length of the smaller canvas is 3 ft and the width is 5 ft. We also know the width of the larger canvas is 10 ft. We don't know the length of the larger, so we can call it x.
3/5=x/10
Cross multiply
3*10=5*x
30=5x
We are trying to find x. To do this, we have to get x by itself. Divide both sides by 5 to cancel out the 5 and leave x by itself.
30/5=5x/5
6=x
So, the length is 6 ft
