Question

2 find the perimeter of the square abcd with vertices shown below in the figure. answer: units

Explanation:

Step1: Determine side - length of square

Count the grid units between two adjacent vertices. For example, between A(2,6) and B(6,6), the side - length $s$ of the square is calculated as the difference in x - coordinates. $s=|6 - 2|=4$.

Step2: Calculate perimeter of square

The formula for the perimeter $P$ of a square is $P = 4s$. Substitute $s = 4$ into the formula. $P=4\times4 = 16$.

Answer:

16
