Question

The base and the hypotenuse of a right angled triangle is 12cm and 20cm.Find its perimeter and area.​

Answer 1

Hey ARMY YOUR ANSWER IS:

Perimeter = 48 cm

Area = 96 cm²

Step-by-step explanation:

In ΔABC,

(AC)² = (AB)²+(BC)²                (Pythagoras theorem)

(20)² = (12)²+(BC)²

(BC)² = 400-144

BC = √256

BC = 16 cm

Perimeter = (12+16+20) cm

= 48 cm

Area of ΔABC = 1/2*b*h

= (1/2*12*16) cm²

= 96 cm²

I  J-HOPE this will help you XD

Answer 2

Step-by-step explanation:

hypo2=base2+height2(let height be x cm)

(20)2=(12)2+(2)2

400=144+x2

x2=400-144

x2=256

x=root 256

x=16

perimeter =20+12+16!

48cm

area=length×breadth

16×12

192cm
