let the sides be 5x 7x so 5x x 7x = 168 =35x=168 now x= 168 ÷35 =4.8 m
But the answer is 35m and 49m

let the sides be 5xand 7x
perimeter,=2(5x+7x)=168
(12x)=168/2
12x=84
x=84/12
x=8m
5x=5*8=40m
7x=7*8=56m
perimeter,=2(5x+7x)=168
(12x)=168/2
12x=84
x=84/12
x=8m
5x=5*8=40m
7x=7*8=56m
sorry but the answer is wrong . The answer is given 35m and 49m
