Question

The length of the rectangle is 10 cm and perimeter is 30 cm, what is the other side

Answer 1

Answer:

W = 5 cm length = 10 com perimeter = 30

Answer 2

• As per the data given in the question, we have to determine the required number.

        Given data:- Length(l)=$10cm.$

                              Perimeter=$30cm.$

        To find:- Breadth(b)=?

        Solution:-

        According to a given condition,

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

        and perimeter of the triangle is $2(length+breadth).$

       Here, we will apply the perimeter of a rectangle, we get

          $\Rightarrow 2(length+breadth)=30\\\Rightarrow 2(10+b)=30\\\Rightarrow 20+2b=30\\\Rightarrow 2b=30-20\\\Rightarrow 2b=10\\\Rightarrow b=5.$

       Hence, the breadth of rectangle is $5cm.$
