Answer:

180 {m}^{2}

Step-by-step explanation:

The area of a trapezoid is given by:

Area =  \frac{1}{2} (sum \: of \: bases) \times h

From the diagram, the bases are 17m 23m, and the the height is 12m.

We substitute the values into the formula to get:

Area =  \frac{1}{2} (17 + 13) \times 12

Area =  \frac{1}{2}  \times 30 \times 12

Area = 6 \times 30

This implies that

Area =  180 {m}^{2}

57 is greater than x - 8
svlad2 [7]

This is an inequality.

This is what the statement should look like: 57 > x - 8

Now, you can actually "properly" reverse these meaning the equality sign changes too. So basically you can mirror them.

The "mirrored" inequality expression would look like this: x - 8 < 57

Now just like normal algebra, you can transpose these terms from 1 side to another and so, -8 would transpose to the right hand side and the operation would be the inverse or in this case, addition. The expression would look something like this: x < 57 + 8

Add them up and you get: x < 65 :D
