What is the area, in square meters, of the trapezoid below?
Sphinxa [80]

Answer: 94.54 m^2 (square meters)

Step-by-step explanation: The formula for the area of a trapezoid is A = 1/2(a+b)h; where a and b are the two top sides of the trapezoid that are parallel. Let us then solve.

Let us combine both sides two maintain the overall side for "b", which is 18 + 5.1 = 23.1

Let us now add both sides (a + b.) 23.1 + 9.5 is 32.6. We can now multiply by the height. 32.6 multiplied by 5.8 is 189.08

We can now divide (or multiply by 1/2), which is 189.08 * 1/2 or 189.08/2 and that equals 94.54.

The number of customers on the first day are (6×-3) the number of customers on the second day is (×-1) how many more customers v
EleoNora [17]

The number of customers who visited more on first day = ( 5 x - 2)

<h2>248 more people visited on the first day. </h2>

Step-by-step explanation:

The total number of customers visiting on first day  = (6 x - 3)

The total number of customers visiting on second day  = (x - 1)

The difference in the number of customers

= Number of customer visiting ( First day - Second Day)

= (6x  - 3) - (x- 1)  = 6 x - 3 - x +  1  = 5 x - 2

So, the number of customers who visited more on first day = ( 5 x - 2)

Now, when x  = 50, ( 5 x - 2) = (5 (50) - 2)  = 250 - 2  = 248

Hence, 248 more people visited on the first day.
