Question

A=bh ; A=42, h=6

Solve B

Answer 1

Hello Tiana:   Just follow the formula, put the numbers where they belong and solve.

 

The formula reads:  Area is equal to base times height.

 

A=  b x h.

 

A= 42  h=6.

 

42=  b x 6.      It says to multiply, so do the opposite which is to divide.

 

42  =  6b.

__      __.

  6        6.         Now cancel the 6 out from top and bottom and we have.

 

7     =   b.      --->    Is your answer.    Now next, put  7  in place of the b  to make each side true.

 

42=  6 x 7.   Does 6  x 7 equal 42?  It must be equal or its a wrong answer.

 

42  =  42 ?   Yes it does, so the answer is correct.

 

Hope this helps.
