Formula
----------------------------------------------------------------------------------------
Area of rectangle = Length x Width
----------------------------------------------------------------------------------------
Find Length
----------------------------------------------------------------------------------------
357 = Length x 17
----------------------------------------------------------------------------------------
Divide by 17 through
----------------------------------------------------------------------------------------
Length = 357 ÷ 7
Length = 51 inches
----------------------------------------------------------------------------------------
Answer: The length of the rectangle is 51 inches
----------------------------------------------------------------------------------------
Write and solve an equation of ratios:
6 inches 1 inch
-------------- = ------------
60 inches x
Cross-multiplying, 6x = 60, so x = 10 inches (answer)
9+3=12
30+20=50
300+100=400
Then add.
12+50+400=462
<span>So 339+123=462</span>
To solve for x, put all of the angle measurements on one side of an equation and set it equal to 360, because the sum of any exterior angles is 360 degrees. hope this helped!
