Zorluk: OrtaGeometric Figures on the Coordinate Plane

In the standard (x,y)(x, y) coordinate plane, a square has two opposite vertices at (1,−3)(1, -3) and (7,5)(7, 5). What is the area of the square, in square units?

Cevap: 50 square units

Cevap

The area of the square is 50 square units.
The length of the diagonal of the square is found using the distance formula between the two opposite vertices: d=(7−1)2+(5−(−3))2=62+82=10d = \sqrt{(7 - 1)^2 + (5 - (-3))^2} = \sqrt{6^2 + 8^2} = 10. The area of a square can be calculated using its diagonal length dd with the formula Area=d22\text{Area} = \frac{d^2}{2}. Substituting d=10d = 10 gives Area=1022=50\text{Area} = \frac{10^2}{2} = 50 square units.
