Answer 3

To find out how long it will take Stas to mow a lawn with an area of 77 square meters, we can set up a proportion based on the given information.

Let x be the number of minutes required to mow the 77 square meters lawn.

We know that Stas can mow a 42 square meters lawn in 6 minutes. So, the proportion will be:

(42 square meters) / (6 minutes) = (77 square meters) / (x minutes)

To find the value of x, we can cross-multiply:

42 * x = 6 * 77

Now, solve for x:

x = (6 * 77) / 42 x = 462 / 42 x = 11

So, it will take Stas 11 minutes to mow a lawn with an area of 77 square meters.
