Triangle pqr has sides measuring 9 feet and 10 feet and a perimeter of 24 feet. what is the area of triangle pqr? round to the nearest square foot. square feet

The answer is 22 square feet :) hope this helps

22 square foot

Step-by-step explanation:

Consider PQR be a triangle, such that PQ=9 feet, PR=10 feet.

Now, Perimeter of triangle=24

⇒Sum of all the sides=24

⇒PQ+PR+QR=24

⇒9+10+QR=24

⇒QR=5 feet

Also, s=

Area of triangle A=

=

=

=

=

≈

thus, area of triangle=22 square foot.

Hi! mark me brainliest if i : )y = 0.213x – 352.0    represents this linear model shown in the data table.plug in the values of x into the equation for a double check.let's try 1980.y = 0.213(1980) – 352.0y = 69.74which is closest to the 70.1 whereas other options do not satisfy the condition.
