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:
A certain shade of pink us created by adding 3 cups of red paint to 7 cups of white paint
Step-by-step explanation:
Constant of proportionality is the constant value of the ratio of two proportional quantities x and y; usually written y = kx, where k is the factor of proportionality.
To make color pink,
for every 3 cups of red , we need 7 cups of white.
Let 'r' be the cups of red required
let 'w' be the cups of white required
so , as per the question
for 3 r we need = 7 w
r = 7/3 w
so, 7/3 is constant of proportionality
Answer:
her mistake is she didn't include pi which will change the number
Step-by-step explanation:
6x2=12
the diameter of the new circle is 12
12x pi or 3.14= 37.68
which is not double the diameter(12) of the circle
A zoo has 14 monkeys and 18 chimpanzees.
To write the ratio of numbers x and y we use three ways given below
1. x to y
2. x : y
3. 
Now write the ratio in three ways comparing 14 monkeys and 18 chimpanzees.
Let x be the number of monkeys
y be the number of chimpanzees
So ratio becomes
14 to 18
14 : 18
