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.
Divide the area by the length of the rectangle
Divide its area by a given side
the area of a rectangle = length x widthwe can rearrange this to give uslength of a rectangle = area/ width
That would depend on the length of the rectangle which has not been given but the area of a rectangle is length times width
Area=b•h
Not enough information given
The breadth of a rectangle is the height.
A rectangle can have only 2 dimensions and so finding the area from the given 4 dimensions has many possibilities.
You cannot.
The area of a rectangle does provide enough information about its dimensions. It is possible fo the rectangle to be long and narrow or squat and short (almost square).
You can't. There are an infinite number of possible rectangles with a given area.
The perimeter of rectangle A would then be 80 because 80 to 100 is 4 to 5 simplified and the area of triangle A would depend on the sides and area of rectangle B which have not been given.
