Question

3. The area of a rectangular field is 300 m². If its breadth is 15 m find (i)its length and (ii) its perimeter .​

Answer 1

Answer:

length- 20m

perimeter-70m

Answer 2

Answer:

$length \: = 20 \: m \\ permeter \: = 70 \: m$

Step-by-step explanation:

$length \: = ? \\ breadth \: = 15 \: m \\ \\ \\ \\ \\ area \: of \: a \: rectangular \: field \: = l \times b \\ 300 \: {m}^{2} = l \times 15 \\ \frac{300}{15} = l \\ \: l = 20 \: m \\ \\ \\ perimeter \: ofa \: rectangular \: field \: = 2(l + b) \\ = 2(20 + 15) \\ = 2 \times 35 \\ = 70$

So, Length is 15 m

and perimeter is 70 m.
