Answer:
Shaded area is 55 units²
Step-by-step explanation:
Ignoring the white cutout, we have a rectangle of length 10 and width 7 (count the squares in each direction). The area of this larger rectangle is
(10 units)(7 units) = 70 units². The white area that we previously ignored has dimensions 3 by 5 units, and thus an area of 15 units²
Subtract the latter from the former, obtaining the net area
70 units² - 15 units² = 55 units²
Answer:
0.430
Step-by-step explanation:
You can create 58 different combinations of line segments from 8 stars make sure each star gets 7 star line segments meaning connect one star with z line segment there should be seven line segments to each star, if you think I have given false or invalid information use other sources in your book or online to get a more accurate answer
Area = L x W
Area = (y+5) (y-5)
Use Foil to multipy (First, Outer, Inner, Last)
Area = y² -5y + 5y -25
Area = y² -25
