Hello!
There are 4 cheetahs. There are 3 times as many elephants than cheetahs. Multiply:
4 • 3 = 12
12 + 4 = 16
Rebecca saw 16 animals at the zoo.
I really hope you found this helpful! :)
Answer:
hold on its its.............oh yeah 21
Answer:
first find the area of the triangle
1/2 base x height
(1/2) 6 x 4 = (1/2) (24) = 12
area of rectangle
base x height
4 x 6 = 24
add them together
24 + 12 = 36
B) 36 inches
hope this helps :)

Answer:

Step-by-step explanation:
The area of a triangle is given by

where
b is the base
h is the height
Here we have an equilateral triangle, which has the 3 sides of the same length.
Let's call L the length of one side.
We know that the perimeter of the triangle is
p = 9 in
The perimeter is the sum of the three sides, so:

Therefore, we find the length of the side:

Therefore the length is the base of the triangle,

The height can be calculated by considering half triangle: the hypothenuse is equal to L, while one side is equal to half the base (b/2), therefore the height is given by Pythagorean's theorem:

Therefore, the area of the triangle is:
