Answer 2

HELLO MATE

HERE IS YOUR ANSWER

SIDES OF TRIANGLE = 11 cm , 60 cm , 61 cm

PERIMETER = 11 cm + 60 cm + 61 cm

= 132 cm

SEMIPERIMETER = 132 cm / 2

= 66 cm.

AREA OF TRIANGLE = √ s ( s - a ) ( s - b ) ( s - c )

= √ 66 ( 66 - 11 ) ( 66 - 60 ) ( 66 - 61 )

= √ 66 * 55 * 6 * 5

= √ 108900

= 330 cm²

AREA OF TRIANGLE = 1 / 2 * B * H

330 cm² = 1 / 2 * 11 * H

H = 330 * 2 / 11

H = 30 * 2

H = 60 cm
