Question

if the triangular plot in ratio 3 : 5 : 7 with its perimeter 300cms find area of triangular plot

please give answer with explanation​

Answer 1

Step-by-step explanation:

first take out your sides

3x+5x+7x=300

15x=300

x=300/15

x=20

3x=3x20=60

similarly

5x and 7 x return

100 and 140 cms

now area

now calculate it

those are the sides

Answer 2

Answer:

100 cm²

Step-by-step explanation:

Let the ratio component be x

3x + 5x + 7x = 300

15x = 300

x = 300/15

x = 20

20*3 = 60 cm

20*5 = 100 cm

20*7 = 140 cm

Area of triangle = 1/2*(base+height)

1/2 * (140 + 60)

1/2 * 200

100 cm²
