Question

The ratio of the length of a school ground to its width is 5:2 Find its length if the width is 40 metres​

Answer 1

Answer:

Given :-

• The ratio of the length of a school ground to its width is 5 : 2.

To Find :-

• What is the length of the width is 40 metres.

Solution :-

Let,

$\mapsto \bf Length =\: 5x$

$\mapsto \bf Width =\: 2x$

According to the question,

$\bigstar$ The width is 40 metres.

So,

$\implies \sf 2x =\: 40$

$\implies \sf x =\: \dfrac{40}{2}$

$\implies \sf x =\: \dfrac{20}{1}$

$\implies \sf\bold{\purple{x =\: 20\: m}}$

Hence, the required length and width is :

$\small \dashrightarrow \sf\bold{\red{Length =\: 5x =\: 5 \times 20 =\: 100\: m}}$

$\small \dashrightarrow \sf\bold{\red{Width =\: 2x =\: 2 \times 20 =\: 40\: m}}$

$\therefore$ The length of a school ground is 100 m .

Answer 2

The length of a school ground is 100m.
