4/5*3/7=a
a=12/35
12/35 square units
0.25 in a fraction would be 1/4
The simplest ratio is 1/3. Equivalent ratios would be 3/9 and 5/15.
Answer:
im not sure what you mean can you elaborate
Step-by-step explanation:
if 1 inch is added, you would add 2 inches to to each side of rectangle.
You would have: W+2, and, L+2,
Now let W+2 = x and, L+2 = y
Total area = x*y=M
If 1 inch is added again, like above you add 2 inches to both sides, you would then have:
(x+2)(y+2)=M+52;
xy+2x+2y+4=M+52;
xy=M
2x+2y=48
x+y=48/2=24
Now solve :
W+2+ L+2=24
W+L=20
The perimeter is 2(W+L)=20*2 = 40 inches.
