Final answer:
To find the approximate area of the wall in square feet, convert the measurements to the same unit. Then, multiply the length and height together to find the approximate area in square feet.
Step-by-step explanation:
To find the approximate area of the wall in square feet, we need to convert the measurements to the same unit. Let's convert the length from inches to feet by dividing it by 12 (since 1 foot is equal to 12 inches).
So, the length of the wall in feet is 90/12 = 7.5 feet.
Now, let's convert the height from centimeters to feet by multiplying it by 0.03281 (since 1 meter is approximately equal to 3.281 feet).
So, the height of the wall in feet is 381 x 0.03281 = 12.52 feet.
Finally, we can find the approximate area of the wall by multiplying the length and height together. So, the approximate area of the wall in square feet is 7.5 x 12.52 = 93.9 square feet.
