If the adjacent sides of a rectangle, whose perimeter is 66 m, are in the ratio 5 : 6, then what will be the area of the rectangle?
Answer & explanation
Correct answer: option 1
Perimeter = 66cm
According to the question,
let the length of the rectangle = 5x
and the breadth of the rectangle = 6x
So, Perimeter of the rectangle = 2( length + breadth)
and Area of a rectangle = length × breadth
2( 5x+ 6x) = 66
5x+ 6x = 33
11x = 33
x = 3
Then the area of the rectangle = length × breadth = (5× 3 × 6 × 3 ) = 270 m2
