Answer:
C=hypotenuse [h]=50 feet
A=[base]=40foot.
B=perpendicular [p]=?
Area =?
we have
By using Pythagoras law
p²+b²=h²
B²=40²=50²
B²=50²-40²
B=√900
B=30feet
we have
Area of triangle =½×A×B=½×30×40=600feet²
<u>the roped off </u><u>area</u><u> </u><u>is</u><u> </u><u>6</u><u>0</u><u>0</u><u> </u><u>square</u><u> </u><u>feet</u><u>.</u>
<u>it</u><u> </u><u>is</u><u> </u><u>a</u><u> </u><u>right</u><u> </u><u>angled</u><u> </u><u>triangle</u><u>.</u>
