The perimeter is the measure of all of the sides added together. If you have a square, the sides are all equal. So, 3+3+3+3= 12 OR 3x4=12. The answer is D.

a million)If the fringe is 36 inches, then, divided through 4, the perimeters might want to be 9 inches each and every. Now, to discover the area, you in straight forward words sq. the perimeters: 9² = 80 one the area is 80 one inches² ======================== 2)For the rectangle, you'll note it has 2 contraptions of equivalent aspects. enable x be the width of the rectangle you're searching for: x + x + 7 + 7 = 35 2x + 14 = 35 2x = 21 x = 10.5 The width is 10.5cm ======================== 3)enable the perimeters of the sq. be x (all aspects of a sq. is equivalent). making use of Pythagoras (note that the diagonal creates a top-angled triangle): x² + x² = 7² 2x² = 40 9 x² = 24.5 x = ?24.5 So the perimeters are ?24.5 ft each and every. To get the area, sq. the perimeters: (?24.5)² The squareroot and the ² cancel out, leaving 24.5 Your area is 24.5 ft²
