Question

What is the area of a rectangle with vertices at (7,3), (12,3), (12,11), and (7,11)?

Answer 1

I hope this helps you

Answer 2

Answer:

Area of Rectangle = Length × Breadth

Distance formula between two points ,

$(x_{1},y_{1}) {\text{and}}, (x_{2},y_{2}), is=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}}$

Length

= Distance between Points ,(7,3) and (12,3)

               $=\sqrt{(12-7)^2+(3-3)^2}\\\\=5$

Breadth

=Distance between Points ,(12,3) and (12,11)

               $=\sqrt{(12-12)^2+(3-11)^2}\\\\=8$

→→Area = 5 × 8

     = 40 square units
