21+28+35 = 84 yd

the area of triangle =

½×21×28 = 294 yd²

The perimeter of rectangle living room is 40 m the living room is 10 m wide what is the length of the living room
Yuri [45]

Answer:

Width of the room = 5 meters

Step-by-step explanation:

the rectangular living room is calculated as length * width

The area is given to be equal to 40 sq. meters (area = 40 sq. meters)

Let the width = x meters

Length = X+3 meters

Area = Length * Width

40 = X * (X+3)

40 = X^2 + 3X

We solve this quadratic equation

So x = 5 or x= -8

Width  cannot be negative, so we reject x =-8

So x = 5 is the answer

This is really a long way to go to make something complicated
out of something simple.  The last choice does the job.

cos(180)  =  -1
sin(180)  =   0

So       4 [cos(180) + i sin(180) ]

       =   4 [ -1      +  i (0) ]

       =     -4     yay!
