Question

the base and the hypoteneous of a right angled triangle are12 cm and 20 cm. find its perimeter and area​

Answer 1

Answer:

Area=96 cm²

Perimeter=48 cm

Step-by-step explanation:

Length of the third side=root(20)²-(12)²

=root(400-144)

Height=16 cm

Perimeter=12+20+16=48 cm

Area=1/2 bh

=1/2 × 12 × 16

=96 cm²

Answer 2

Answer:

IN ANGLE ABC,

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

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

BC 2 = (12) 2 + ( BC) 2

BC 2 = 400- 144

BC = 256

BC = 16 cm

PERIMETER = (12+16+20)cm

= 48 cm

AREA OF ANGLE ABC = 12 * b* h

(12 * 12 * 16 ) cm 2

=96 cm 2

sorry because I am write square to 2 ok

my 2 is square

It's hope full
