Answer 1

Step-by-step explanation:

$\tt\red{ QUESTION}$$\tt\blue{::}$

perimeter of a rectangle is 80 m and its length 25 find its breadth and area

$\tt\red{ ANSWER}$$\tt\blue{::}$

$p = 80m \\ l = 25m \\ 2b = (p - 2l) \\ 2b = 80 - 2(25)m \\ 2b = 80 - 50 \\ 2b = 30 \\ b = 30 \div 2 \\ b = 15$

Hence,breadth=$\tt\red{ 15}$$\tt\blue{meter}$

$l = 25 \\ b = 15 \\ area = (l \times b ) {m}^{2} \\ (25 \times 15) {m}^{2} \\ = 375m {}^{2}$

Hence, area=$\tt\red{ 375}$$\tt\blue{m²}$

Answer 2

$\tt\red{ QUESTION}$

perimeter of a rectangle is 80 m and its length 25 find its breadth and area

\tt\red{ ANSWER}

\begin{gathered}p = 80m \\ l = 25m \\ 2b = (p - 2l) \\ 2b = 80 - 2(25)m \\ 2b = 80 - 50 \\ 2b = 30 \\ b = 30 \div 2 \\ b = 15\end{gathered}

Hence,breadth=

\tt\red{ 15}

\begin{gathered}l = 25 \\ b = 15 \\ area = (l \times b ) {m}^{2} \\ (25 \times 15) {m}^{2} \\ = 375m {}^{2} \end{gathered}

\tt\red{ 375}
