Question

if the sides of the field is the ratio 3;4:5 in and its semi perimeter is 72 m. what is the area of the field?​

Answer 1

72

Step-by-step explanation:

(3x+4x+5x)/2 = 72 => x = 12

(3,4,5) is a triplet of Right angle ∆ so the field will be right triangular in shape.

area = 1/2 * 3x * 4x = 6x = 6(12)

= 72 m^2
