Triangle square & rectangle
Perimeter is the distance around an object and area is the amount of space/volume in an object (square,rectangle,triangle)
The perimeter of the square is 96.
the area of a rectangleis 100 square inches. The perimeter of the rectangle is 40 inches. A second rectangle has the same area but a different perimeter. Is the secind rectangle a square? Explain why or why not.
The perimeter is the sum of all four sides, so you need to calculate 2 x length + 2 x height. The fact that the rectangle is at the bottom of a triangle is irrelevant - except that in specific diagrams, information may be provided that lets you calculate the length or the width of the triangle.
