You question is does not make sense. The base is a straight line , NOT an area. You either want the Area of the rectangle or the Length of the base. The Area of a rectangle is found by multiplying the base (length) to the width(height). A = lW (or BH) Algebraically rearrange to find the base length B = A/H ( That is area divided by height).
Area of a rectangle= length x height.For example:A 2' by 4' rectangle would have an area of 2 x 4 = 8 square feet.As a formula, it is L*W=A.
The length of a rectangle is twice its width. If the perimeter of the rectangle is , find its area.
the length of a rectangle is 5 more then the width. Find the perimeter and the area of the rectangle
You would also need to know the area of rectangle, along with the width in order to determine the length of the rectangle.
find the perimeter and area of a rectangle that is 15cm long and 5cm wide
in order to find area of rectangle=(len*bred)
To find the area of the shaded part in a rectangle, you first find the total area of the rectangle by multiplying its length by its width. Then, you subtract the area of the non-shaded part from the total area to get the area of the shaded part. The formula would be: Area of shaded part = Total area of rectangle - Area of non-shaded part
To find the area of a rectangle, you simply multiply its length by its width. In this case, the length is 21m and the width is 17m. Therefore, the area of the rectangle would be 21m x 17m = 357 square meters.
you need length and width length multiply width = area length + length + width + width = perimeter
