Question

Length is 5cm and area is 15cm² find the breadth,perimeter

Answer 1

Answer:

3cm,16cm

Step-by-step explanation:

l=5,a=15

lb=a

5×b=15

b=3

p=2(l+b)

=2(5+3)

=2×8

=16cm

Answer 2

Answer:

breadth = 3 cm

perimeter = 16 cm

Step-by-step explanation:

length = 5 cm

area = 15 cm²

using formula:

AREA = length x breadth

area = 15 cm²

l x b = 15

5 x b = 15

b = 15/5

breadth = 3 cm

perimeter = 2 ( l + b )

= 2 ( 5 + 3 )

= 2 ( 8 )

= 16 cm
