a football field is drawn to a scale of 1cm represents 5cm if the field is 70m by 50m find the length and breadth on the drawing​

length of the drawing will be 14cm and breadth will be 10cm.

Step-by-step explanation:

if actual 5m represents 1cm in drawing then,

5m = 1cm

1m = 1/5cm

70m = (1/5)×70cm =14cm

likewise,

50m = (1/5)×50cm =10cm

thus, length in drawing is 14cm and breadth in drawing is 10cm.

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
