Answer:
The perimeter of a rectangle is the total length of all four sides.
To find the perimeter of a rectangle with length 4x+2 and width 7y-7, we use the formula P=2L+2W where L is the length and W is the width.
Therefore, P=2(4x+2)+2(7y-7)=8x+14y-10. Thus, the perimeter of this rectangle is 8x+14y-10.
Explanation:
Identify the given values of the rectangle: the length is 4x+2 and the width is 7y-7.
Use the formula for perimeter to calculate the perimeter: P = 2(L + W)
Substitute the given values into the equation: P = 2(4x+2 + 7y-7)
Simplify the equation: P = 2(4x + 7y - 5)
Solve for the perimeter: P = 8x + 14y - 10 Therefore, the perimeter of the rectangle is equal to 8x + 14y - 10.
