L=1.5w
P=l+w
40=2.5 w
W=16
L=1.5(16) =24

Length is 24
Width is 16

Length and width of the rectangular laboratory is equals to 12m and 8m respectively.

<h3>What is rectangle?</h3>

"Rectangle is defined as the quadrilateral whose pair of opposite sides are parallel and congruent to each other. Each angle is of measure 90°."

Formula used

Perimeter of the rectangle = 2( length + width)

According to the question,

Perimeter of the rectangular laboratory = 40m

'l' represents the length of the rectangular laboratory

'w'  represents the width of the rectangular laboratory

As per the given condition we have,

l= 1\frac{1}{2} w

 = \frac{3}{2} w

Substitute the value in the formula of the perimeter we get,

   2(l + w) = 40

⇒ (l +w) = \frac{40}{2}

⇒ ( \frac{3}{2} w+ w) =20

⇒\frac{5}{2} w= 20

⇒w= 8 m

Therefore,

l= \frac{3}{2} (8)

  =12m

Hence, length and width of the rectangular laboratory is equals to 12m and 8m respectively.
