Answer:
5•x=? and 8•5=40, personal opinion: the left rectangle is most likely a square so if you need to solve it it's 5•5=10
Step-by-step explanation:
A(area)=l (length)•w (width)
just plug in your numbers, in this case it would be 8(length) times 5(width)
The board is 12x larger in length than the nails. (Since the width of the board and nails are unknown, I am assuming you mean the length, not area difference)

AS L || M
so here 38° + m<1 = 180°
so m<1 = 180°-38°
m<1 = 142°
But if you r asking what would be there in place of green box then your answer is 142 .
HOPE IT HELPED YOU.
C 59.5 because 8.5-1.5 =7 and 10-1.5=8.5 multiply 8.5x7=59.5 formula of the area of the rectangle is Length times width
