What is the area of the following trapezoid in square feet?
2 answers:
Answer:
135 ft^2 (first answer choice)
Step-by-step explanation:
Convert the length of the 7 yd base to feet: 21 ft.
Then the average length of the trapezoid is (15 ft + 21 ft)/2 = 36/2 ft = 18 ft.
The area of the trapezoid is then (average length)(height), or
A = (18 ft)(7.5 ft) = 135 ft^2 (first answer choice)
Answer:
82.5 ft²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = 
h (b₁ + b₂)
where h is the perpendicular height and b₁, b₂ the parallel bases
Here h = 7.5, b₁ = 7 and b₂ = 15 , then
A = × 7.5 × (7 + 15) = 0.5 × 7.5 × 22 = 82.5 ft²

the original price is "x", or 100%.
but we know that if we reduce "x" by 20%, namely 100% - 20% = 80%, the 80% of "x" is really £50, what is "x" or the 100% anyway?
Answer:
you are already in the hundredths
Step-by-step explanation:

5= the ones place
4= the tenths place
8= the hundredths
2*3+4=10
5+2x2=9
4-3+2=3
4*3+2=14
20-4x3+6=14
16-30/2+11=12
24/6*5=20
15/5+2=5
2+2*9-5=15
12-3+4*2=1
12/3+3*4=16
