Brainstorm: How much base molding is required for this room? What formula would you use? Brainstorm: What other type of construction mathematic applications could this be used for?

B RAINSTORM : W HAT AREAS WOULD YOU BREAK THIS SHAPE UP INTO TO CALCULATE THE FLOOR AREA MINUS THE CORNER FIREPLACE ?

Let’s Discuss It S OLUTION : U SING THE FORMULA FOR PERIMETER WE WILL ADD ALL SIDES TOGETHER TO DETERMINE THE LINEAR FEET OF MOLDING NEEDED. S1= 5’ +3’+5’=13’ S2-6= 9’+10’+8’+10’+9’= 46’ 46’+13’=59’ T HIS APPLICATION COULD ALSO BE USED TO CALCULATE FOR W ALL PAPER BORDER OR CROWN MOLDING.

A B C D SOLUTION: T HE AREA COULD BE BROKEN DOWN AS FOLLOWS A REA A: T RIANGLE A REA B : S QUARE A REA C; R ECTANGLE A REA D: ½ C IRCLE

Formulas C IRCLE : PIE R SQUARED BUT IT IS A HALF CIRCLE SO DIVIDE BY 2

SQUARE & RECTANGLE SQUARE AND RECTANGLE ARE BOTH LENGTH X WIDTH

TRIANGLE ½ BASE X HEIGHT

IN CONCLUSION USING BASIC MATH CALCULATIONS ITEMS SUCH AS THE FOLLOWING CAN BE ESTIMATED FOR CONSTRUCTION WALL AREA MOLDING LENGTH FLOOR AREA CEILING AREA
