Answer:
AREA = 30cm^2
Step-by-step explanation:
PR^2 = PQ^2 + QR^2
PQ^2 = PR^2 - QR^2
PQ^2 = (13)^2 - (5)^2
PQ^2 = 169 - 25
PQ^2 = 144
PQ = 12
AREA OF TRIANGLE PQR
= 1/2×5×12
= 30 cm^2
hope this helps

In Triangle PQR
By pythagoras thereom ,
(PR) ^2 =( PQ)^2 + (QR)^2
25 = PQ^2 + 169
25 ‐ 169 = PQ^2
144 = PQ^2
PQ = 12 cm
Base = 5 cm
Height = 12 cm
Area of triangle = 1/2 × base × height
= 1/2 × 5 × 12
= 6×5
= 30 cm^2
.: Area of triangle PQR is 30 cm per square .
HOPE IT HELPS YOU :‐)
