Answer:
5in
Step-by-step explanation:
The formula for area is A=bh or Area = Base × Height
or you can write it as A=wh which is Width × Height
so plug in the numbers you already know
(do not worry about units right now)
45=b(9)
Now you have to get the variable b by itself
divide both sides by 9 to get b by itself
45(÷9)=b(9)(÷9)
the 9 next to the b gets canceled out
45÷9= 5
The answer is 5 inches
Always remember that the actual area's units are squared while the base and height are just the unit not squared
45in²=area
5in and 9in= base and height
