Answer:
The answer to your question is At = 48 + 36
Step-by-step explanation:
Area = Area of the base + Lateral area
a) Area of the base
Area = length x height / 2
length = 12
height² = 12² - 6²
= 144 - 36
= 108
height =
= 6
Area = 12 x 6
= 36
b) Lateral area
height² = 10² - 6²
= 100 - 36
= 64
height = 8
Area = 12 x 8/2
= 48
c) Total area
At = 48 + 36
Answer:
15% = 3/20 = 0.15
1.25 =125% =5/4
12 3/8 = 12.375 = 1237.5%

Its super easy all u have to do is go on tiger math and the first link will take you to it and u put in the question and it will give you a step by step how to do it and it will give you the answer
X + 12 = 20
x + 12 -12 = 20 -12
x = 8
6.8/5 = 1.36
1.36 x 8 = 10.88
This means that the cost of an adult is $10.88
