Question

the sides of a triangle plot are in ratio 3:5:7 and perimeter 15300m .find the area of plot

Answer 1

First find the sides of the triangle.
3x + 5x + 7x = 15300
15x = 15300
15300/15 = 1020
3(1020)= 3060m
5(1020)=5100m
7(1020) = 7140 m
These are the sides of the triangle.
After that find the area by 1/2bh
