One side of a square measures 15 cm. What is its area

225

Step-by-step explanation:

A true square has all equal sides. With all equal sides the there would be four 15cm sides. Area of a square is length*width. 15*15=225

225cm²

Step-by-step explanation:

A square is a type of quadrilateral( polygon with 4  sides) that has all his sides equal.

Area of a square = length x breadth

But since all sides are equal

Therefore breadth = length

This means that area of square = length x length or area = square of the length

Given that length= 15cm

Therefore area of the square = 15cm x 15cm

Area = 225cm²

Area of a square with length 15cm is 225cm²

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
