Question

find the area of rectangle using distributive property 4x20

Answer 1

                   Hi Lennox  ..I'll take a crack at this....

 

             The area of a rectangle is A= (LxW) (4x20),  80= (4x20)  or

 

     a(b+c)   =  (ab   +ac)  so lets break down the numbers...   lets try...

 

    a=4

 

  b=10

 

   c=10

 

           4(10 + 10)           = (4)  *  (10)     +   (4)  *  (10)

 

      =  4(20)                   =         40          +         40            =80

 

 

                Hope this helps
