Welcome to Catalytic, a blog to discuss the discussion of subject matter from Higher Education, High School, Middle School and Elementary Schools. This time Katalistiwa will discuss a question that is often asked in school exams. The questions are: **The area of the shaded area is**

In this problem we will study the area of a simple flat shape

**Formula :**

Wide rectangle length = length x width

Area of triangle = x base x height

### Detailed explanation of Rectangle Area Problems

Is known :

Rectangular :

length = 32 cm

width = 15 cm

Right triangle :

base = 16 cm

height = 7.5 cm

Asked:

The area of the shaded region?

Answered:

To find the area of the shaded region, we first calculate the area of the entire rectangle, then subtract the area of the right triangle.

Rectangular :

length = 32 cm

width = 15 cm

Area of rectangle = length x width

= 32 x 15

= 480 cm²

Right triangle :

base = 16 cm

height = 7.5 cm

Area of triangle = x base x height

= x 16 x 7.5

= 60 cm²

= Area of rectangle – Area of right triangle

= 480 – 60

= 420 cm²

So the shaded area is 420 cm² (C)
