Answer:
Step-by-step explanation:
1) Perimeter of a plane shape is the distance round the shape. The formula for the perimeter of a square is expressed as
Perimeter = 4 × length of one side
Since the length of one side is given as 10 inches,
The perimeter = 4×10 = 40 inches.
2) the side lengths of the triangle are 2x -7, 5x -3 and 2x -2. The formula for the perimeter of a rectangle is expressed as
a + b + c
Where a,b and c are the length of the sides of the triangle.
Perimeter = 2x -7 + 5x -3 + 2x -2 = (9x -12) inches
3) if x=6, the perimeter of the triangle would be
9×6 -12 = 54 - 12 = 42 inches
