Question

what is the area of square bcde? area = square units

Explanation:

Step1: Determine side - length

Count the number of grid units between two adjacent vertices. The horizontal distance between B(1,3) and E(-7,3) (or vertical distance between B(1,3) and C(1, - 5)) is 8 units.

Step2: Use area formula

The area formula for a square is $A = s^2$, where $s$ is the side - length. Here $s = 8$. So $A=8^2$.

Step3: Calculate the area

$8^2=64$.

Answer:

64
