Hey, Guys, can someone help me with this
Lunna [17]

Answer:

A length=24ft, width=15ft

Step-by-step explanation:

the side AB have x values of 5 and the side with CD have x values of 10 so the width from b to d or a to c is 5 so the width of the drawing is 5cm

the bottom side AC has y values of 8 and the top side BD has y values of 16 so they are 8 apart so the length of the rectangular drawing is 8cm

then the scale says that 1 cm = 3 ft so multiply the length and width each by 3 to get the answer that the length of the sail is 24ft and the width is 15ft

Hope this helps! :)

John dana and douglas painted a room
they have combined effort so
john+dana+douglas=total room

total room=100%=1/1=1
so 1 whole=8/8 so
2/8 is painted by john so they don't need to paint that so
so
2/8+dana+douglas=8/8
subtract 2/8 frm both sides
dana+dogluas=(8-2)/8=6/8
dana+douglas=6/8
dana painted same as douglas so divide by 2
dana=douglas=3/8


so A is 6/8 or 3/4
B is 2/8+3/8+3/8=8/8 or 2/8+dana+douglas=8/8
