Answer:
1,100 is your area
Step-by-step explanation:
First we cut the shape into three, two triangles and a square, the formula to find the area of a square is A=a^2 (a is the side)
A=25^2
A=625
now to find the triangles the formula to find the are we use the right angled triangle formula twice which is A=a*b/2
A=25*19/2
A=475/2
A=237.5
now add them all up
625+237.5+237.5=
1,100
The expressions 100×10 and the more complicated
(100 - 4a)(10 + a)
are calculating annual (expected) revenue. In 100×10 the 100 is the number of decks and the 10 is the price per deck. In (100 - 4a)(10 + a) the 100-4a is the number of decks and the 10+a is the price per deck. So a must be the amount the price increases.
Answer: amount of price increase, last choice
