Question

the perimeter of a rectangle is 40cm and its area is 96sq. cm. calculates its length and breadth​

Answer 1

Answer:

l = 16 and b=6

Step-by-step explanation:

area = l × b

so the length and breadth should be factors of 96.

perimeter = sum of all sides.

so the addition of factors of 96 should be 40 so that numbers are 16 and 6.

:. l =16 and b=6

Answer 2

Answer:

Length=12

Breadth=8

Step-by-step explanation:

Perimeter=2[l+b]

2[ l+b]=40cm

l+b=20cm

Taking length as half of [l+b]

l=10+x

b=10-x

Area=96

[10+x] {10-x]=96

10* - x*=96

100-x*=96

100-96=x*

4=x*

x=2

length=10+2=12

breadth=10-2=8
