Answer:
If the long side is down then the length of the base is 81 sq.m.
If the short side is down then the length of the base is 20.25 sq.m.
Step-by-step explanation:
162/4 is 40.5 that means if this were a square it would be 40.5 sq.m. On each side, if the base is longer you multiply 40.5 by 2 (or whatever youre supposed to honestl) and if the base is shorter you divide by 2 (or whatever you were supposed to)
Answer:
The polygons are similar.
Step-by-step explanation:
By definition, the corresponding sides and angles of similar polygons must be in some constant proportion.
Therefore, we can find the ratio between corresponding sides to see if that ratio is maintained.
The side marked 3 cm in the smaller figure corresponds with the side marked 3.75 cm in the larger figure. This proportion is
.
The side marked 5 in the smaller figure corresponds with the side marked 6.25 cm in the larger figure. This proportion is
.
If these polygons are similar, these proportions must be equal.

Checking, we see that these proportions are equal, and therefore the polygons are similar.
Answer:
Step-by-step explanation:
Quotient of a and 399 : 
181 times z = 181*z = 181z
Equation:

He sold all general admission tickets
Can prove using simultaneous equations
50x + 60y = $1050
x + y = 21 => y = 21-x
50x + 60(21-x) = 1050
50x + 1260 - 60x = 1050
-10x = 1050 - 1260
-10x = -210
x = -210/-10
x = 21
x + y = 21
21 + y = 21
y=0
Since he sold 21 general admission tickets and no VIP tickets
