The equation you are thinking of is for a trapezoid or parallelogram. Rectangles have 4-90 degree angles and two different side lengths, so unless the picture is drawn to scale and you have a ruler, you cannot figure out the "height," or adjacent side of the rectangle. You may be able to figure it out by drawing a diagonal line through the rectangle and using sine/cosine/tangent to figure out the sides and angles, but it doesn't seem like you have enough information to do so. However, area of a rectangle is determined by the following equation: Length x Width = Area. So if you know the length (base) and the area, you can simply divide the area by the base and you will most likely have the answer.

How do you find the area of a rectangle when given the base and height?
Multiply them by eachother.
What is an area of a base of 7 centimeters and a height of 12?
If it is a rectangle then area = base × height = 7cm × 12 cm = 84 cm². If it is a triangle (more likely given the terminology used) then area = ½ base × height = ½ × 7 cm × 12 cm = 42 cm²
Can you explain why the area of a triangle is 1 half base height while the area rectangle or a parallelogram is expressed as base height?
If you draw a diagonal in a rectangle you get two equal triangles, each half the area of the rectangle. Area of rectangle is base x height, so half of that is ½ x base x height. QED
How do you find the base of a rectangle when you no the area and the height?
Divide the area by the height
Can you find the area of a rectangle if the problem doesn't show you the base and height?
The one alternative to find the area of a rectangle is when you are given the length of one diagonal and its slope.

Which formula for the area of a parallogram is similar to a rectangle circle triangle ellipse or trapezoid?
Rectangle Area of parallelogram = Base * Height Area of rectangle = Base * Height

Why is the area of a rectangle base times height?
A rectangle is a good, simple shape to begin with. The area of a rectangle is equal to the product of the length of its base and the length of its height. The height is a segment that is perpendicular to the base. For a rectangle, the base and height are often called the "length" and the "width", and sometimes the height is referred to as the "altitude."

What is the area of a rectangle with a base of 30in and a height of 4yd?
The area of rectangle is : 120.0
What is the base of a rectangle with height of 4 and area of 28?
7. Since the area of a rectangle is base x height, the base must be the area (28) divided by the height (4). 28/4 = 7
How do you find the height of a rectangle with the base and perimeter given?
Height = (Perimeter/2) - Base
What is Area of the base times the height?
rectangle
