To find the area of Mr. Steven's lawn, which is in the shape of a parallelogram, we need to use the formula for the area of a parallelogram. The formula is:
[tex]\[ \text{Area} = \text{base} \times \text{height} \][/tex]
Given the dimensions of the parallelogram:
- The height (perpendicular distance) is 9 feet
- The base is 15 feet
Now we substitute these values into the formula:
[tex]\[ \text{Area} = 15 \, \text{feet} \times 9 \, \text{feet} \][/tex]
Multiplying these together gives us:
[tex]\[ \text{Area} = 135 \, \text{square feet} \][/tex]
Therefore, the area of Mr. Steven's lawn is 135 square feet.
