While there are an infinite number of rectangles, possible dimensions with integral measurements are: 1 by 24 (perimeter = 50 units), 2 by 12 (perimeter = 28 units), 3 by 8 (perimeter = 22 units), and 4 by 6 (perimeter = 20 units). Perimeter: 74 centimeters, Area: 231 cm 2 1-45.
a: Yes, it is correct because the two angles make up a 90° angle. a: 6x + 6 b: 6x + 6 = 78, so x = 12 and the rectangle is 15 cm by 24 cm. If he left them outdoors, they will still be dead because it has not rained for 2 weeks, so he needed to water them once a week as well. If his plants are indoors, they will be dead because he will be gone for 2 weeks and so he did not water them at least once a week. No – if the points are collinear then they will not form a triangle. Possible responses include “They have 3 sides of equal length” and “They have 3 angles of equal measure.” 1-16. Possible responses include “How many sides does it have?”, “Does it have a right angle?”, “Are any sides parallel?” 1-15. Possibilities: Goes to bank, gets money from parent, gets paid buys lunch, goes shopping, pays a bill, … Shapes (a), (c), (d), and (e) are rectangles.
