Question

Find the area of Traingle plot whose side in the ratio of 3:5:7 and its perimeter is 300 m

Answer 1

perimeter= sum of all sides

300= 3x + 5x + 7x

300=15x

300/15=x

20=x

3x=3x20

= 60m

5x=5x20= 100m

7x=7x20=140m

area=1/2x base x height

=1/2x 140 X 100

=70x100

= 7000 m square

Answer 2

hey dear, here's ur ans....

The area of triangle plot whose side is in the ratio of 3:5:7=3x, 5x, 7x.

The perimeter is 300m..

3x+5x+7x=300

15x=300

x=300/15

x=20

First plot= 3x= 3*20=60m

Second plot= 5x= 5*20=110m

Third plot=7x=7*20=140m

hope it helps u...
