Question

graph square efgh with vertices e(5, -1), f(5, 10), g(-6, 10), and h(-6, -1).
what is the area of square efgh?
area = \square square units

Explanation:

Step1: Find the length of a side

For vertical side \(EF\) (same \(x\)-coordinate), use \(y\)-coordinates. \(F(5,10)\) and \(E(5, -1)\), length \(= 10 - (-1)=11\). Or horizontal side \(FG\) (same \(y\)-coordinate), \(F(5,10)\) and \(G(-6,10)\), length \(= 5 - (-6)=11\).

Step2: Calculate area of square

Area of square \(= \text{side}^2\). So, \(11^2 = 121\).

Answer:

121
