Two different squares have an areas of 36m° and 49m°
sleet_krkn [62]

The difference of the length of two different squares having area of 36 square meters and 49 square meters is 1 m.

According to the question,

We have the following information:

Two different squares have an area of 36 square meters and 49 square meters.

We know that the following formula is used to find the area of square:

Area = side*side

Side*side = 36

Side = √36

Side = 6 m

Now, side of the another square:

Side*side = 49

Side = √49

Side = 7 m

Now, the difference in the length of the sides of these two squares:

7-6

1 m

Hence, the difference of the length of two different squares having area of 36 square meters and 49 square meters is 1 m.
