Answer 1

$\boxed{Question:-}$

Rita runs around a rectangular park (180 x 80) m. Anuj runs a square park 160 m long. Who runs more distance and How much distance they covered?

$\boxed{Solution:-}$

Area of Rectangular Park - Area of Square Park=Total Distance they covered↓

→Rectangular Park↓

length(l)=180m

breadth(b)=80m

→Area of Rectangle=l×b

→180×80=14400m²

→Square Park↓

Side(a)=160m

→Area Of Square=a²

=>(160)²=25600m²

25600-14400=11200m²

=>Anuj Ran More and by 11200m²

Answer 2

$\huge{\underline{\underline{\bf{Solution}}}}$

$\rule{200}{2}$

$\tt Given\begin{cases} \sf{Dimensions \: of \: rectangular \: field = (180 \times 80)m^2} \\ \sf{Dimension \: of \: square \: park = 160 \: m} \end{cases}$

$\rule{200}{2}$

$\Large{\underline{\underline{\bf{To \: Find :}}}}$

We have to find the distance covered by Rita and Anuj. Who covers more distance and by how much.

$\rule{200}{2}$

$\Large{\underline{\underline{\bf{Explanation :}}}}$

We know that,

$\Large{\star{\boxed{\sf{Area = Length \times Breadth}}}}$

$\sf{\mapsto Area = 180 \times 80} \\ \\ \sf{\mapsto Area = 14400 \: m^2}$

$\sf{\therefore \: Distance \: by \: Rita \: is \: 14400 \: m^2.}$

$\rule{200}{2}$

Now,

$\Large{\star{\boxed{\sf{Area = Side \times Side}}}}$

$\sf{\mapsto Area = 160 \times 160} \\ \\ \sf{\mapsto Area = 25600 \: m^2}$

$\sf{\therefore \: Distance \: covered \: by \: Anuj \: is \: 25600 \: m^2}$

$\rule{200}{2}$

Anuj covers more distance than Rita

→ 25600 - 14400

→11200 m²
