now,

=》Area of trapezium =

\frac{1}{2}  \times sum \: of \: parallel \: sides \times height =》[tex] \frac{1}{2}  \times (x + 20) \times 16 = 400

=》( x + 20 ) × 8 = 400

John earned three dollars for each lawn he mowed. If he had eight lawns to mow, but forget mow two of them, how much money did h
gayaneshka [121]
If John had to mow 8 lawns, but he forgot to mow 2 lawns, we have to subtract 2 from 8 to see how many lawns he actually mowed.

8-2=6

John mowed 6 lawns!

For each lawn John mowed, he earned 3 dollars. So, we have to multiply the number of lawns he mowed, 6, by the amount of dollars he earned per lawn, 3. Multiplying 6*3 is the same as adding 3+3+3+3+3+3!

6*3=18

John earned $18!

Hope I helped! :)
