Question

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

Answer 1

Answer:

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
