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

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

Answer»

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.
