Question

PQR is a triangle, right angled at P if PQ = 10cm & PR =24cm, find QR.
​

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:

Perpendicular = PQ = 10 cm

Base = PR = 24 cm

Hypotenuse = QR

Now to find QR we will use Pythagoras theorem

Hence QR = 26 cm.

Answer 2

Given :-

• PQR is a triangle, right angled at P.
• Length of PQ=10cm
• Length of PR=24cm

To Find :-

• Length of QR

Solution :-

Perpendicular = PQ = 10 cm

Base = PR = 24 cm

Hypotenuse = QR

Now to find QR we will use Pythagoras theorem

$\bf Hypotenuse^2=Perpendicular^2+Base^2$

$\longmapsto \sf QR^2=PQ^2+PR^2$

$\longmapsto \sf QR^2=10^2+24^2$

$\longmapsto \sf QR^2=676$

$\longmapsto \sf QR=\sqrt{676}$

$\longmapsto \sf QR=26$

Hence QR = 26 cm.
