Question

If the area of rectangle is 54 m2
and its width is 75 cm find its lenght in metres​

Answer 1

Answer:

72 m

Step-by-step explanation:

Area of rectangle = 54 m² = 540000 cm²

Breadth/width of the rectangle = 75 cm

Length of the rectangle = $\frac{Area}{Length/Width}$ = ( $\frac{540000}{75}$ ) cm = 7200 cm = 72 m

Answer 2

• As per the data given in the question, we have to find the area of a rectangle.

        Given data:- Area=$54m^{2}.$

                             Width=$75cm.$

         As we know that, $1m=100cm.$

         Using conversion of unit,we get

         Width in meters=$\frac{75}{100}=0.75m.$

        To find:- the area of rectangle=$54m^{2}.$

         Solution:-

• As we know, the area of rectangle is $length\times breadth.$

• Here, we will apply the area of rectangle formula.

        Therefore,

        Area of Rectangle=$Length\times breadth$

                $\Rightarrow 54=l\times b\\\Rightarrow 54=l\times0.75\\\Rightarrow l=\frac{54}{0.75}\\\Rightarrow l=72m.$

      Hence, the length of rectangle is $72m.$
