You can work out the diagonal by using Pythagoras theorem. (a^2 = b^2 + c^2)
As it is a square, all 4 sides are the same so it would be:
11.2^2 + 11.2^2 = diagonal^2
250.88 = diagonal^2
Square root both sides to get what the diagonal is equal to.
diagonal is 15.8 cm

Step-by-step explanation:
To multiply decimals, begin by multiplying the numbers as if there is <u>no decimal</u>:

Count the number of digits <u>after</u> the decimal point in each factor:
- 128.5 → 1 digit after the decimal point.
- 3.24 → 2 digits after the decimal point.
Therefore, there is a total of 3 digits after the decimal points.
Put the same number of digits after the decimal point in the product.
Therefore, the solution is to the multiplication is:
The factor with the <u>fewest signification figures</u> is 3.24.
This number has 3 significant figures.
Therefore, the solution to 3 significant figures is:
