MARK ME AS BRAINLIST#

Area of rectangle = area of circle.

Now,

Length of rectangle = 14 cm.

Breadth of the rectangle = 11 cm.

Area of rectangle = length × breadth

⇒ 14 × 11

⇒ 154 cm²

Now,

Area of circle = 154 cm²

⇒πr² = 154 cm²

\begin{lgathered}⇒ \frac{22}{7} \times r {}^{2} = 154 \\ \\ ⇒22r {}^{2} = 154 \times 7 \\ \\ ⇒22r {}^{2} = 1078 \\ \\ ⇒r {}^{2} = \frac{1078}{22} \\ \\ r {}^{2} = 49 \\ \\ ⇒r = \sqrt{49} \\ \\ \therefore r = 7\end{lgathered}⇒722×r2=154⇒22r2=154×7⇒22r2=1078⇒r2=221078r2=49⇒r=49∴r=7 

Hence, radius of circle = 7 cm


williamdinh1: it isnt about the circles just rectangles tho
williamdinh1: I am trying to find the dimensions of rectangles in which the approx area when rounded is the same as the actual area of the rectangle
ye72: sorry
williamdinh1: Could you try again?
