From the information given in the question you may not assume that the shape is rectangular. It could, for example, be a isosceles triangle with sides of 7.3, 7.3 and 11.4 cm.
Area = 289 sq cm so length of side = sqrt(289) = 17 cm Then perimeter = 4*side = 4*17 = 68 cm
6 cm * 10 cm
Well if what you are asking is whether you would use perimeter or area to measure a set amount of wallpaper the answer is area; e.g. 1 sq. ft. of wall paper
Any positive value upto 36 square units. A 6x6 square will have the maximum area of 36 sq units; a 5x7 rectangle will have an area of 35 sq units, and the area will be reduced as you reduce one of the measures and increase the other so that their sum remains 12 units so that the perimeter is 24 units. 1x11 will be 11 sq units 0.1x11.9 will be 1.19 sq units 0.01x11.99 will be 0.1199 sq units 0.001x11.999 will be 0.011999 sq units, etc.
14 cm
9 sq cm
Perimeter = 104 cmArea = 676 sq cm.
A 4 ft by 9 ft rectangle
120 sq cm
36 cm2 Area of a rectangle is length times width, so you would multipy 12cm by 3 cm to get 36 sq. (squared) cm.
60 sq cm
12cm x 12cm originally (144 sq cm area)
The perimeter is 10 + 3 + 10 + 3 = 26 in. The area is indeterminate because a quadrilateral is not a rigid shape and can be "squished". The area is anything between 0 and 30 sq inches.
30 sq cm ((12 x 5)/2)
If the perimeter is 32 sq cm, there is a very serious problem since the perimeter is a linear measure, not an area! Leaving that aside, the length of the rectangle is 10 cm and the breadth is 6 cm.
The perimeter of a square with an area of 25 sq ft is 20 feet because each side of the square is 5 feet, so the perimeter must be 4 x 5 feet.
The perimeter is not going to have sq units. If the perimeter of a square is 15 units then the area would be 14.0625units squared.
