The answer will depend on the shape of the triangle and what is known about it.
s+s=d-s+pRULE
in order to find the area of a rectangle you must multiply the base of the rectangle by its height. This is also the same for most polygons
Area of rectangle with part of the shape missing = area of rectangle (lengthxwidth)-area of missing part.
The area of a triangle is expressed using the formula A=(1/2)(bh) Where A is area Where B is length of the base of the triangle. Where H is the height of the triangle. The area of a rectangle is A=BH, Where B is the length of the base of the rectangle. Where H is the height of the rectangle. Because a triangle, essentially, is a half of a rectangle, you find the area of the whole rectangle that the triangle comes from, then divide that in half.

The length of a rectangle is twice its width. If the perimeter of the rectangle is , find its area.
By using area of a rectangle do you remember in 7th grade when you had to do this:Area of RectangleA=LxWlenght x width
By using that one thing.
the length of a rectangle is 5 more then the width. Find the perimeter and the area 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)
In order to find the area of a rectangle, multiply the length by the width of the rectangle. For example: If the length of a rectangle is 5cm and the width of a rectangle is 2cm, then the area of the rectangle would be 5cm X 2cm = 10cm².
