Given:
Diameter of circle = 14cm
Radius of circle = 14/2 = 7cm
Area of circle = $\mathit{\pi }\times \mathit{r}\mathit{a}\mathit{d}\mathit{i}\mathit{u}{\mathit{s}}^2$
Area of circle = $\left(\frac{22}{7}\right)\times 49=154\mathit{c}{\mathit{m}}^2$
According to question:
Area of circle = Area of rectangle
Area of rectangle = length × breath
Breath of rectangle = 11cm
⇒ $154=11\times$ length
⇒ Length = 14cm
∴ Required value is 14cm
