In this question, there are numerous information's of immense important already given. Based on those given information's the answer to the question can be easily deduced.
Ratio of the perimeter of two rectangles = 4:7
Perimeter of the larger rectangle = 42 inches
Let us assume the common ratio = x
Then
7x = 42
x = 42/7
= 6
Then
Perimeter of the smaller rectangle = 4 * 6 inches
= 24 inches.
So the perimeter of the smaller rectangle is 24 inches. I hope the procedure and the answer is clear enough for you to understand. Based on this procedure, you can attempt similar problems without requiring any outside help.
Answer:
16
Step-by-step explanation In mathematics the difference is the result of subtracting one number from another, and represents the operation of removing objects from a collection:
If the base of the tank is a square, then the length and width are the same, making the area length*width*height=length*length*8=length^2*8=1268. Dividing both sides by 8, we get length^2=158.5 and by square rooting both sides we get length=sqrt(158.5)=around 12.6 for the length (and width), and 8 feet for the depth/height
Let s represent the short side of the triangle. The long sides of the triangle are each s+1, and the triangle's perimeter is
... s + (s+1) + (s+1) = 3s+2
The length of one side of the square is s-2, and its perimeter is 4 times that, 4(s-2) = 4s-8. The square and triangle have the same perimeter, so
... 3s+2 = 4s-8
... 10 = s . . . . . . . . add 8-3s to both sides
The length of the shorter side of the triange is 10 units.
