Question

the length and breadth of a triangular fieldare 3:4 if the area is 6912m² then the perimeter of the field is _________

Answer 1

let the ratio be multiplied by x
so, 3 *x : 4*x .
so, area = L*B
6912 m square = 12x
6912/12 =x
x = 576
perimeter= 2(L+B)
2(4*576 +3*576)
2*(2304+1728)
5760

Answer 2

let the ratio be multiplied by x

so, 3 *x : 4*x .

so, area = L*B  

6912 m square = 12x

6912/12 =x

x = 576

perimeter= 2(L+B)

2(4*576 +3*576)

2*(2304+1728)

5760
