Question

triangle PQR is right angled at Q If PQ=10cm and QR=24cm.Find the area of triangle PQR

​

Answer 1

Answer:

26 cm

Step-by-step explanation:

Given : PQR is a triangle, right angled at P.

To Find:If PQ=10cm and PR=24cm, find QR

Solution:

Refer the latched figure

Perpendicular = PQ = 10 cm

Base = PR = 24 cm

Now to find QR we will use Pythagoras theorem

Hypotenuse = QR

Hypotenuse^2=Perpendicular^2+Base^2

QR^2=PQ^2+PR^2

QR^2=10^2+24^2

QR^2=676

QR=\sqrt{676}

QR=26

Hence QR = 26 cm.
