Question

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

Answer 1

Given expressions:

Area of a rectangle = L W

Area of a triangle =
`(1)/(2) B H`

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 =
`(1)/(2)` x length =
`(1)/(2)` 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 =
`(1)/(2)` x b x h

Area of a triangle =
`(1)/(2)` x 30 x 2 = 30cm²

The area of the triangle will be 30cm²
