Question

if the sides of a triangle are in the ratio 5:12:13 and it's perimeter is 450m find it's area

Answer 1

Sides of the triangle =12x+13x+5x=perimeter

12x+13x+5x=450
30x=450
X=15

First side =12*15=180
Second side =13*15=195
Third side =5*15 =75

find its area.....

Answer 2

Answer:

Step-by-step explanation:

5x+12x+13x=450 m

30x = 450

X=450/30

X= 15

5×15=75

12×15=180

13×15=195

Area of triangle= 1/2 × base× height

= 1/2× 75×180

=6750 m²
