Answer:
If you rotate the triangles so that they look the same, one side of both of them are labeled. This gives you the fraction 9/12, or 3/4. The smaller triangle is 3/4th of the larger one. If the larger triangle has 4 on one side, then let's make the equation 3/4 = y/4. The length of y is 3. :)
The length and the width of the rectangle are 22 inches and 16 inches respectively
<h3>How to determine the length and the width of the rectangle?</h3>
The given parameters are:
Length = 6 inches + width
Perimeter = 76 inches
The perimeter is calculated as:
Perimeter = 2 * (Length + Width)
This gives
76 inches = 2 * (6 inches + Width + Width)
Divide through by 2
38 inches = 6 inches + Width + Width
Evaluate the like terms
2 * Width = 32 inches
Divide both sides by 2
Width = 16 inches
Substitute Width = 16 inches in Length = 6 inches + width
Length = 6 inches + 16 inches
Evaluate
Length = 22 inches
Hence, the length and the width of the rectangle are 22 inches and 16 inches respectively
