The side length of the square is 2*((8/2)^.5) = 4cm
The area is 4^2 = 16 cm

See the attached picture. The parts labeled a and b are both the same length since this is a square. And each of them is half of the side length of the square. We can find the length of a and b using the Pythagorean theorem because the 8cm is a hypotenuse of a right triangle. So we find a, and multiply by 2 to get the square side length. Then we square that to get the square area.

Mary242 made for 11 hours of work.
MAVERICK [17]

We conclude that, if working at the same rate, to make 374 units, she needs to work for 17 hours.

<h3>At the same rate, how many hours would she have to work to make 374?</h3>

We know that Mary makes 242 units of something in 11 hours of work, then her rate of work is:

R = (242 units)/(11 hours) = 22 units per hour.

Now, if she wants to make 374 units, then she needs to work for a time T, such that:

(22 units per hour)*T = 374 units.

Solving that linear equation for T, we get:

T = (374 units)/(22 units per hour) = 17 hours

We conclude that, if working at the same rate, to make 374 units, she needs to work for 17 hours.
