Question

10. Find the area of a rectangular park whose length and breadth are 15 and 11
m and 11 m, respectively​

Answer 1

Answer:

Area of rectangle: length× breadth

length:15 m, Breadth: 11m

15×11=165m²

Answer 2

✤ Given ✤

$\begin{gathered}\bullet\ \sf{Length\ of\ a\ rectangular\ park=15\dfrac{2}{3}\ m }\\\\\bullet\ \sf{Breadth\ of\ the\ rectangular\ park=11\dfrac{1}{2}\ m }\end{gathered}$

✤ To Find ✤

$\sf{The\ area\ of\ the\ rectangular\ park.}$

✤ Solution ✤

$\sf{We\ know,\ for\ a\ rectangle,}$

$\boxed{\sf{\color{magenta}{Area=Length \times Breadth}}}$

$\textsf{Substituting the values :-}$

$\begin{gathered}\sf{\longrightarrow A=15\dfrac{2}{3}\times11\dfrac{1}{2} }\\\\\sf{\longrightarrow A=\dfrac{(3\times15)+2}{3}\times \dfrac{(2\times11)+1}{2} }\\\\\sf{\longrightarrow A=\dfrac{45+2}{3} \times \dfrac{22+1}{2}}\\\\\sf{\longrightarrow A=\dfrac{47}{3} \times \dfrac{23}{2}}\\\\\sf{\longrightarrow A=\dfrac{1081}{6} }\\\\\boxed{\boxed{ \color{lime}{\sf{\longrightarrow A= 180\dfrac{1}{6}\ m^2}}}}\end{gathered}$

$\begin{gathered}\mathbf{Hence,\ the\ area\ of\ the\ rectangular }\\\mathbf{\ park\ is\ 180\dfrac{1}{6}\ m^2.}\end{gathered}$

OR

Given

Length of rectangle = 15 ⅔ m

Breadth of rectangle = 11 ½ m

Find out

Area of rectangle

Solution

As we know that

★ Area of rectangle ★

➟ Length × breadth

➟ 15 ⅔ × 11 ½

➟ 47/3 × 23/2

➟ 1081/6

➟ 180.16 m²

Hence,

Area of rectangle is 180.16 m²
