Question

please find fast and tell the correct answer ​

Answer 1

perimeter=186cm,

p of rectangle=2(l+b),

l=2x+66,

b=5x+6,

186=2((2x+66)+(5x+6)),

186=2(2x+66+5x+6),

186=2(7x+72),

186=14x+144,

14x=186-144,

14x=42,

x=42/14=21/7=3,

x=3,

Now ATQ, l=2x+66=2(3)+66=6+66=72,

b=5x+6=5(3)+6=15+6=21
