Question

the length of rectangle is 27 metre longer than its breadth if the perimeter of rectangle is 110 M then find its area

Answer 1

let breadth of rectangle = b
length = b+ 27
perimeter = 110
2( l+b) = 110
2 ( b + 27 + b) = 110
2b = 28
b = 14
l = b+ 27
l = 14 + 27 = 41
so it's area = l× b = 14 × 41 = 574 m^2
