Think about how to find the area of a rectangle. A=LW and a triangle 1/2B*H. Create a problem using each formula.

Given expressions:

  Area of a rectangle  = L W

  Area of a triangle =

Problem;

Create problems using the formula;

Solution:

Problem 1; Find the area of a rectangle whose length is 10cm and the width is half the size of the length?

    Given parameters:

    Length of rectangle  = 10cm

    Width of rectangle  = x length  = x 10  = 5cm

So, the area of the rectangle = 10cm x 5cm  = 50cm²

2. A triangle with a base length of 30cm and a height of 2cm will have an area of what?

    Given parameters:

         base length  = 30cm

         height  = 2cm

 Solution:

   Area of a triangle  = x b x h

   Area of a triangle  = x 30 x 2  = 30cm²

The area of the triangle will be 30cm²
