Answer:
The area of the rectangle is 27
Step-by-step explanation:
so we need our formula to find the area of a rectangle. Area = Width × Length
Now we plug our numbers in.
A = 9 × Length
Since we are missing our exact Length amount we need to figure that out first. The statement says the length is 1/3 the size of the Width and the Width is 9.
9 × 1/3 = 9/3
9/3 can be simplified to 3 thus our Length is 3. now we add this into our equation
A = 9 × 3
A = 27
Step-by-step explanation:
-Twice means muliply by 2
-The difference of a number and 7 means subtract a number/variable and 7.
-Is equal to 9 means =9
2(X - 7) = 9
