B5: Analyze problem situations involving measurement concepts, select appropriate strategies, and use an organized approach to solve narrative and increasingly complex problems.

More simply put: Find strategies to solve simple problems about some kind of measurment that can be used no matter how difficult the problem is.

Problem 1: If a rectangle has a base of 5 cm and a height of 4 cm, what is the area of the rectangle?

Work: To find the area of a rectangle, you must multiply the base length by the length of the height. So, in this case you need to multiply 5 cm by 4cm, which is 20. Area is always expressed in the units you have measured squared.

Answer: 20 sq.cm.

However, depending on what type of figure you are measuring the formula for finding its area would change.

Formulas for Finding Area in Different 2-d Figures: (b=base h= height a=area)

Square: Multpiply one of its dimensions by itself once. (d=dimension)
a=d×d

Triangle: Multiply the base by the height,and then divide that product by 2.
a=bh÷2

Trapezoid: FInd the average of the bases, then multiply that by the height
a=b#1+b#2÷2xh

Circle: Find the radius of the circle. Square that number and then multiply that product ,of that equation by pie. (r =radius)
a= r×r×3.14
