Answer 1

Answer:

60 x 130

Step-by-step explanation:

             w

           ____

           |         |

w+70   |         |   w+70

           |         |

           ---------

                w

add all the sides

2(w+70)+2w=380

2w+140+2w=380

4w+140=380

move the 140 to the other side of the =

4w=380-140

4w=240

divide both sides by 4

w=60

to get the length plug in 60 to w+70   to get 130 and width is just 60.
