A rectangle with a length of 12 cm and a width of 6 cm has an area of 72 sq cm and a perimeter of 36 cm.

frozen [14]

So we should first start off by checking for the ones with the same area, which is 72sq cm

80×90=7200sq cm so A is incorrect

8×10=80sq cm so B is incorrect

3×24=72sq cm so, so far C is correct

4×14=56sq cm so D is incorrect

And because all are incorrect except C
Then C is the correct answer, just to be sure, we will check the perimeter

24+24=48
48+3=51
51+3= 54

So the perimeter is different, making C the correct answer

Which statement illustrates the distributive property? Please help

bogdanovich [222]

It's letter C

Addition, you can have 6 + 107 = 113 
Commutative Property by moving: 107 + 6 = 113 
Associative Property by grouping: (3 + 3) + (100 + 7 ) = 113 
Distributive Property by allotting: 2 (3) + 107 = 113 

Multiplication, you can have 6 x 107 = 642 
Commutative Property by moving: 107 x 6 = 642 
Associative Property by grouping: (3 + 3) x (100 + 7 ) = 642 
Distributive Property by allotting: 2(3) x 107 = 642
