Question

What is the area of this rectangle?

Enter your answer in the box. Enter only the numerical answer (do not enter units).

Answer 1

Answer:
Area = 50

Step-by-step explanation

we need to find the length of the rectangle from (4 , -3) to (-1,7)

`√((4+1)^2+(7+3)^2) = √(25+100) = √(125) = 5√(5)`

∴
`length = 5√(5)` units

breadth of rectangle from (-1,7) to (-5,5)

`√((-1+5)^2+(7-5)^2) = √(16+4) = √(20) = 2√(5)`

∴
`breadth = 2√(5)` units

Area of rectangle = length * breadth

=
`5√(5) * 2√(5)`

= 50 sq.units
