A small square cloth has an area of 361 cm2. Sarah sewed four of them together to form a larger square cloth. What is the perimeter of Sarah’s larger square cloth?

152 cm

Step-by-step explanation:

Once again its a square. All sides are equal.

Square root 361 to get 19.

19 x 19 = 361

4 was sewed together.

You could either add, 361+361+361+361

Or you could multiply, 361 x 4

Either way you get 1444.

You could either square root 1444 to get the side length or you could add the previous side length to itself once to get the new side length of 38.

Now you need to get perimeter.

P=4 x length

P=4 x 38

152 cm
