What is the area and perimeter of a square when l12.3 and w31?

The area of a rectangle of length 12.3 and width 31 is 12.3 X 31 = 381.3, the perimeter of the same rectangle is 2(12.3+31) = 86.6.


If a rectangle has a perimeter of 80 cm and a length of 31 cm what is the width?

To find the width of the rectangle, we can use the formula for the perimeter, which is ( P = 2 \times (length + width) ). Given the perimeter is 80 cm and the length is 31 cm, we can set up the equation: ( 80 = 2 \times (31 + width) ). Simplifying this gives ( 40 = 31 + width ), so the width is ( 40 - 31 = 9 ) cm. Thus, the width of the rectangle is 9 cm.

We don't know. The perimeter doesn't uniquely define the dimensions. It could be: 1 x 35 2 x 34 3 x 33 4 x 32 5 x 31 10 x 26 15 x 21 15.39 x 20.61 . . etc. All of these rectangles have a perimeter of 72.


How do you find the width and perimeter of a rectangle if the length is 31 cm and the width is 5 less than one half of the length?

Let's call the length L and the width W. The width is 5 less than half of the length, so W = (1/2)L - 5. The length is 31, so W = (1/2)(31)-5, which is 10.5. So the length is 31 cm and the width is 10.5 cm. The perimeter is 2 lengths and 2 widths, so the perimeter equals 2L + 2W. In this case, it is 2(31) + 2(10.5) which is 83 cm.
