Is it sometimes always or never true that the perimeter of a rectangle is numerically greater than its area?
Sometimes. Experiment with a small square and with a large square (though any shape rectangle will do). A square of 4 x 4 has a perimeter of 16, and an area of 16. A smaller square has more perimeter than area. A larger square has more area than perimeter.
What is the area of a trapezoid if the perimeter is 32?
Unlike a square, knowing the perimeter of a trapezoid is not enough to be able to calculate its area. Think of a rectangle with a perimeter of 20cm. One possibility is that it has a length of 8cm and a width of 2cm. This would give and area of 16cm2. However the rectangle could have also had a length of 7cm and a width of 3cm as this would also give a perimeter of 20cm. However this rectangle now has an area of 21cm2. To be able to calculate the area of the trapezoid, you would need to know more about it than just its perimeter.
What is the perimeter for a polygon that's area is 20sq. units?
Even if you knew how many sides the polygon has, you stillcould not calculate its perimeter with that much information.Examples:-- An equilateral triangle with area of 20 has perimeter of 20.3885 .-- A square with area of 20 has perimeter of 17.889(rounded).-- A rectangle with area of 20 can have any perimeter more than 17.889 .4 by 5 . . . . area = 20, perimeter = 182 by 10 . . . area = 20, perimeter = 241 by 20 . . . area = 20, perimeter = 42..etc.
What is the length of rectangle is 8 in more than its width the perimeter of the rectangle is 24 in what are the width and length of the rectangle?
10x2
The perimeter of a rectangle is 116 cm The base is thirteen more than two times the base What is the area?
