What is the area of a rectangle 10 mm wide and 10 cm long?
10mm*10cm = 1cm*10cm = 10 square cm.
What is the area of a rectangle if its 8cm long and 5cm wide?
area = 8*5 = 40 square cm
What is the area of a rectangle with 9 units wide and 10 units long?
The area of a rectangle is length times width.In this case, it is 10 x 9 = 90 square units.
Draw 2 rectangles for the perimeter of 10cm one with the least area and one with the greatest area?
The greatest area is when the rectangle is a square. A perimeter of 10cm equates to each side of square measuring 2.5cm and then the area = 2.52 = 6.25 sq cm. The least area occurs when the rectangle is shaped like a long, narrow slit. So that the length is as close to 5cm as possible and the width is as narrow as possible. Let's say that the length is 4.9 cm and the width 0.1 cm, then the area = 4.9 x 0.1 = 0.49 sq cm. If these dimensions are changed slightly to length 4.95 and width 0.05 then the area = 4.95 x 0.05 = 0.2475 sq cm. As the length gets closer to 5 then the width gets closer to 0 and the area becomes almost 0 sq cm.
What is the perimeter of 23cm long and 10 cm wide?
Well, honey, the perimeter of a rectangle is calculated by adding up all the sides, so for your 23cm long and 10cm wide rectangle, you just add up all the sides: 23 + 23 + 10 + 10 = 66cm. Voilà, you've got yourself a perimeter!
