The problem uses the perimeter formula. P = 2w + 2l where w is the width, and l is the length.
We know the length (l) is 3 inches longer than it's width (or l = w+3). Substitute w +3 into Perimeter equation
P = 2w + 2(w+3). That simplifies to P = 4w + 6.
Since P + 42, we have 42 = 4w +6. With some simple algebra we find that w = 9 and l = 12.
Hope this helps!
Answer:
t=4
Step-by-step explanation:
solve for t by deciding both sides by k.
then do 144/36 to get t.
25% of 30 can be found by converting 25% to a decimal and multiplying it by 30.
25% = 0.25
30x0.25=7.5
So x is 7.5.

Ratio is a comparison of two values or two quantities.
Fraction is a another form of ratio.
The first term and the second term in the ratios are important.
It should not be changed.
The first quantity value is in first term and the second quantity value is in second term of the ratio.
Ratio and fractions are same.
Example:
The ratio of male to female in the school is 5 : 6.
5 represents male students and 6 represents female students.
The fraction form of the above ratio is 
Tan46=x/12
12×tan 46=x
12×1.03=x
0.21255=x
