Welcome to the article A rectangular stained glass window is made up of identical triangular parts as pictured below. On this page, you will learn the essential and logical steps to better understand the topic being discussed. We hope the information provided helps you gain valuable insights and is easy to follow. Let’s begin the discussion!
Hence, the area of shaded region is:
72 square inches.
We have to find the area of the shaded region i.e. we have to find the area of a triangle.
Clearly the shaded triangle is in the shape of a right triangle.
we will firstly find the dimension of the triangle in order to find it's area.
Clearly the base(b) of a triangle is 36/4= 9 inches.
( since the side of the rectangle of length 36 inches is divided into 4 equal parts)
similarly the height(h) of the right triangle is:
48/3=16 inches.
( since the side of rectangle of measure 48 inches is divided into 3 equal parts)
Hence, the area of triangle is calculated as:
[tex]Area=\dfrac{1}{2}\times b\times h\\\\\\Area=\dfrac{1}{2}\times 9\times 16\\\\Area=72\text{square\ inches}[/tex]
Hence, the area of shaded region is:
72 square inches.
