Answer:
length = 10.2 m , width = 6.8 m
Explanation:
the perimeter is the sum of the 4 sides of the rectangle.
the opposite sides of a rectangle are equal
let width be w , then length is 1.5w
given perimeter = 34 , then
2(1.5w) + 2w = 34
3w + 2w = 34
5w = 34 ( divide both sides by 5 )
w = 6.8
and length = 1.5w = 1.5 × 6.8 = 10.2
dimensions of room : length = 10.2 m , width = 6.8 m
