The perimeter of rectangle BCDE is units.

Answer 1

Area of the rectangle is 96.05 sq.units , The ratio of the areas is 2/3 , Area of rectangle ABEF is 64.03 sq.units.

The complete question is

In the figure, the ratio of the area of rectangle ABEF to the area of rectangle ACDF is(a)_____ . If the coordinates of point A are (0,6), the area of rectangle ABEF is(b)____ square units, and the area of rectangle ACDF is(c)____ square units.  The perimeter of rectangle BCDE is(d)____ units.

What is a Rectangle ?

A rectangle is a polygon with four sides and for angles and four vertices , Its opposite sides are parallel and equal.

The  area of rectangle ACDF is square units. = ?

The perimeter of rectangle BCDE is units. = ?

$\rm d = \sqrt{ (y_2 -y_1 )^2 + (x_2 -x_1)^2}\\\\\rm d = \sqrt{ (2 - 6 )^2 + (5 - 0)^2}$

d = 9.605

the length of  $\rm EF$

$\rm FE$ = 10 units.

and $\rm FD$ = 15 units

Area of a Rectangle $\rm ACDF$ is given by

Length x width

10 * 9.605

Area of the rectangle is 96.05 sq.units

Perimeter of a rectangle is = 2( length + breadth)

ED = FD-FE = 15- 10 = 5 units

Therefore

Perimeter = 2 ( 5 +  √41 )

Perimeter = 22.81 units

Area of rectangle ABEF is 64.03 sq.units

The ratio of the areas

= 64.03/96.05

= 0.666667

= 2/3
