Step-by-step explanation:
step 1. this is a trapezoid. the area A = (b1 + b2)h/2 where b1 is the bottom base and b2 is the top base (per se), and h is the height. this formula is the definition of the area of a trapezoid.
step 2. A = (b1 + b2)h/2 = (22 + 9)(5)/2
step 3. A = 31(5)/2 = 155/2 = 77.5in^2.

It is an irrational number.
As a decimal, it equals 1.414235... This is a nonrepeating and nonterminating decimal, which makes it an irrational number, It also cannot be represented as a ratio of two integers.
For the first picture using Pythagorean Theorem, we know that a^2 + b ^2 = c^2 but since we only know c ( 99.2) and b ( 62 ) we need to use the theorem to find a the equation we use for that is :
A = square root of ( c^2 - B^2 )
A = 77.44
A snowflake falls 90 feet in 1 minute.
60 ÷ 4 = 15
6 x 15 = 90
