Answer:

93 days between them. 93 is a multiple of 7, so they will fall on the same day.

Step-by-step explanation:

30 days in april, 31 days in may, 30 days in june.

Altogether that is 93 days. So 93 days from april 1st, will be the same day, since 93 is a multiple of 7.

Find the area of the parallelogram, find the area of the triangle, then subtract the triangle's area from the area of the parallelogram.

Area of Parallelogram:
A= base * height
A= 20 in * 10 in
A= 200 in^2

Area of Triangle:
A= 1/2 base * height
A= 1/2 (10 in)(9 in)
A= 1/2 (90)
A= 45 in ^2

Area of Poster Left:
subtract the difference
A= Parallelogram Area - Triangle Area
A= 200 in^2 - 45 in^2
A= 155 in^2

ANSWER: 155 in^2 is the area of the poster board she has left.

Hope this helps! :)
