Question

the perimeter of a triangle is 480m and it sides are in the ratio 1:2:3 find the are area

Answer 1

Step-by-step explanation:

Perimeter=480m

1x+2x+3x=480

6x=480

x=80

The three sides are 80,160 and240

Using herons formula

area=√s(s-a)(s-b)(s-c)

here s=240 m

area=√240(240-80)(240-160)(240-240)

=0
