Assuming that you want to minimise the perimeter, then use a square. Its side length is, of course, given by the square root of the area.
The dimensions for area are [L2]

Find the dimensions of the rectangle of largest area that can be inscribed in a circle of radius a in C programming
Multiply length by width
You can't tell the dimensions of a rectangle from its area, or the dimensions of a prism from its volume.
The new dimensions are 4cm and 7cm
Area = 2*5 = 10 square inches
i don't know sis
Length of rectangle garden is 5 m greater than the width. the area is 84 m2. find the dimensions of the garden.
The dimensions are 10 m by 6.5 m and so 10*6.5 = 65 square m
If those are the dimensions of a rectangle, simply multiply length times width.
Rectangles don't have depth. If your figure has three dimensions, divide the area by the product of the two dimensions you know. The quotient will be the third dimension.
