Question

The perimeter of a triangle
is 144 m and the ratio of the
sides is 3:4:5. Find the area of
the field? *
0 800 sq cm
O 824 sq cm
O 864 sq cm
O 854 sq cm​

Answer 1

Answer:

hope it will help you

Step-by-step explanation:

The lengths of the sides of a triangle are in the ratio 3 : 4 : 5 and its perimeter is 144 cm. Let the sides be a = 3x , b = 4x and c = 5x . Hence, the area of the field is 864 cm²

Answer 2

here if we take 3x one side , 4x another, 5x the other then the perimeter is 12x

so 12x is equals to 144 (given) so x equals to 12

so area of triangle is half intu base intu hight by using that formula you can find the answer
