Can someone help me answer these? thank u

perimeter = 36 yd

x+5+x+8+x-1 = 36

3x+12=36

3x=24

x=8

pq= 16

pr=13

qr=7

Step-by-step explanation:

The perimeter given can be used to find sides lengths because perimeter of a triangle is calculated by adding all three side lengths together

So x + 5 + x + 8 + x - 1 = 36 yd add the like terms

3x + 12 = 36 yd

3x = 24

x = 8

PQ = x + 8 ➡ 16

QR = x - 1 ➡ 7

PR = x + 5 ➡ 13

only 10/60 isn't equivalent

hope this : )

this is answer of 144 cubic meters
