Question

the area of a rectangle is 285m length 15m find breadth​

Answer 1

Answer:

area of rectangle = l× b

285m² = 15 m × b

285m²/15 m = b

19m = b

b = 19 m

Answer 2

Step-by-step explanation:

${\huge \bigstar\boxed{ÀÑSWÉR } \bigstar}$

Length = 15 CM

Breadth = Not given

To Find Breadth we do =>

$area \: of \: rectangle = l \times b \\ 285 {m}^{2} = 15 \times b \\ \frac{285}{15} = b \\ b = 19m$

So, Breadth is 19 m..

Perimeter is =>

$perimeter \: of \: rectangle \: = 2( l+b ) \\ = 2(15 + 19) \\ = 2 \times 34 \\ = 68 \: m$

So,Perimeter is 68 m.

hope it's help you...
