I need to see the shape so I can help
3.7 x 4.1 x 10 = 151.7 cm2
Answer:
c) 5√2 cm
Step-by-step explanation:
A square with side length l has a perimeter given by the following equation:
P = 4l.
In this question:
P = 20
So the side length is:
4l = 20
l = 20/4
l = 5
Diagonal
The diagonal forms a right triangle with two sides, in which the diagonal is the hypothenuse. Applying the pytagoras theorem.




Lenght is a positive meausre, so




So the correct answer is:
c) 5√2 cm
Your answer would be letter C
Here are different ways to rewrite the sum;
First, 45+90=135
-46+89
-47+88
-46+87
