Answer:
The line segment 7 cm long is shown below.
Step-by-step explanation:
First we draw a line line segment whose length is 7 cm long. Then we divide the line in small parts. 
The length of each part is 1 cm.
Six points on the line segment divides the line in 7 equal parts and length of each part is 1 cm.
From the figure it is noticed that we have total 7 small parts and length of each part is 1 cm. So length of 7 parts is

Hence the total length of line is 7 cm.

Okay so 
area of picture= 192cm
area of frame= 40×24=960
960÷ 192= 5
Therefore the picture is 1/5 of the frame.
 Length of picture = 1/5 × 40 = 8cm
 Width of picture = 192/8 = 24
The dimensions of the picture are then 8cm × 24 cm.

Answer:
no. 
Step-by-step explanation:
since 2 of the sides are much longer than the shorter sides, diagonals of a rectangle will not intersect at a right angle (perpendicular) whereas a square, with all sides equal, would. This is because the distance from the center to each of the corners is the same for each corner.
