Length of a rectangle is 3 in longer than the width when the perimeter is 54 inches

Mathematics

Let width be x, 
Length: 3+x 

P=2(l+w) 
54=2(x+(x+3)) 
54/2=2x+3 
27=2x+3 
27-3=2x 
24=2x
24/2=x 
12=x 

Therefore, the width is 12 inches and the length is (12+3)=15 inches

Hope I helped :)

#2 Find the area.<br> 10ft
den301095 [7]

Answer:

It would be 78.539...

Step-by-step explanation:

So the equation for area is π r^2. We don't have the radius but we have the diameter. Since the radius is always 1/2 of the diameter, simply divide 10/2 to get this.

Now with the radius, it can simply be plugged into the equation for the answer:

π r^2,

π 5^2,

π 25

78.539...
