Question

find the perimeter and length of rectangle whose breadth is 14 and area is 210 all in centimetre

Answer 1

area of rectangle =l×b

then 14×x=210

x=210/14

x= 15cm

and l=15

perimeter of rectangle =2 (l+b)

=2 (15+14)

=2 (29)

=58cm

Answer 2

Answer:

l = 15cm

perimeter = 58 cm

Step-by-step explanation:

l *b = 210

l * 14 = 210

l = 210/14

l = 15

perimeter = 2( l + b)

2(14 + 15)

2 (29)

58 cm
