Question

if triangle length 3:4:5,then that area of triangle is____square unit, where triangle perimeter is 144 unit. explain...​

Answer 1

Answer:

864

Step-by-step explanation:

Let the ratio be 3x:4x:5x.

Perimeter = Sum of all sides

=> 3x+4x+5x = 144

=> 12x = 144

=> x = 12

Hence, the sides are 36, 48 and 60.

Area = 1/2 × Base × Height = 1/2 × 36 × 48 = 864
