Question

If the given rectangle is an equable shape, then the value of y is

when x=10​

Answer 1

Given:

• Rectangle is an equable shape.

• Value of $x = 10 \ cm$

To Find:

• The value of y

Solution:

Equable rectangle

• an equable rectangle has its perimeter and area numerically equivalent.

$x \ cm$ and $y \ cm$ are length and width respectively of the rectangle.

Perimeter of rectangle $= 2 (x + y) cm$

Area of rectangle $= xy \ cm^2$

The given rectangle is equable,

So,

            $2 (x + y) = xy$

           $2 (10 + y) = 10y$

                $10 + y = 5y$

                $5y - y = 10$

                      $4y = 10$

                       $y = 2.5$

Therefore, the value of y is 2.5 cm.
