Question

the area of rectangular lawn is the same as the area of an 18 M long square if the length of the rectangular lawn is 27 metre find its perimeter

Answer 1

ar(square)=ar(rectangle)
18×18=324
ar(rectangle)=324
27×?=324
?=324
$\frac{324}{27}$
12 is breadth
2(l+b)=perimeter of rectangle
2(27+12)=78
perimeter is 78

Answer 2

If area of square and rectangle are same then,
Area of square = side sq
= 18 sq
=324 Sq m
Breadth= area / length
=324/27
=12m
Perimeter = 2(l+b)
2(27+12)
78m
