Question

The perimeter of a rectangle is 25 metres and one of its
side is 5 metres. How many metres is the other side?​

Answer 1

➣ AnSwer :-

Measurement of the other side :-

$\longrightarrow \sf \: \frac{25}{5}$

$\longrightarrow \sf \cancel \frac{25}{5} = \frac{5}{1} = 5m$

Therefore,the other side measures 5 metres.

Answer 2

$\mathrm{Area\:of\: rectangle\:=}$$\mathrm{2(L+b)}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 25 = 2(5 + b)$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 25 = 10 + 2b$

$2b = 25 - 10$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 2b = 15$

$b = 15 \div 2$

$b = 7.5$

Otherside is 7.5cm.
