The answer is 36 m.
This is really simple. To solve, multiply the length and the width and BAM! There's your answer. So for this problem, multiply 12 by 3 and don't forget to include the unit measurement.
12 * 3 = 36
Area = 36 m
Hope this helps! :)
Answer:
1) The mistake u made is in the work step 2 when u transposed 4 to the side of 12 you should have changed the sign. It should have been multiplication.
2) Just recheck it once.
So, x was 48
Step-by-step explanation:
Equation:
x/4 - 5 = 7
Transpose 5 first.
So,
x/4 = 7 + 5
(Remember to change the sign when u transpose 5 to the RHS)
So,
x/4 = 12
Transpose 4.
So,
x = 12 × 4
x = 48
Recheck,
Substitute x with 48
48/4 - 5 = 7
Let's check:
48/4 = 12
Now 12 - 5 = 7
So, 7 = 7
Hope it helps
