Question

find the length and perimeter of are rectangle if it's breadth and area are 19m and 475m​

Answer 1

Step-by-step explanation:

Area of rectangle =

$l \: \times b$

$475 = l \times 19$

$l = \frac{475}{19}$

$l = 25 \: m$

Hence, length of the rectangle is 25 m.

Now,

Perimeter of rectangle

$= 2(l + b)$

$= 2(25 + 19)$

$= 2 \times 44$

$= 88$

Hence, the perimeter of the rectangle is 88 m.

Answer 2

Answer:

Area of rec= 475m

Breadth= 19m

length = ?

Step-by-step explanation:

Area = L x B

475 = L× 19

L = 475/19

L = 25m

Perimeter of rec = 2( l + b)

= 2(25+19)

=2(44)

= 88 m2.
