Question

the areas of a rectangle is 96cm2 if the breadth of the rectangle is 8cm find its lenght and perimeter​

Answer 1

Answer:

Lenght=12cm and Perimetre=40cm

Step-by-step explanation:

Area =96cm2 and breadth =8cm

so,area=l*b

96=l*8

96/8=l

therefore,lenght=12cm

Perimetre=2(l+b)

P=2(12+8)

P=2*20

Therefore,perimetre=40cm

Answer 2

Answer:

$\huge{\boxed{\rm{\red{Length=12 cm}}}}$

$\huge{\boxed{\rm{\red{Perimeter=40 cm}}}}$

Step-by-step explanation:

Given:-

The area of a rectangle is 96cm² and the breadth of the rectangle is 8cm .

To find:-

find its lenght and perimeter.

Solution:-

Let the length of the rectangle =X cm

Breadth of the rectangle=8 cm

The area of the rectangle =l×b sq.units

=>Area =8X cm²

According to the given problem

Area of the rectangle =96 cm²

=>8X=96

=>X=96/8

=>X=12 cm

Length =12 cm

Perimeter of the rectangle=2(l+b) units

=>Perimeter=2(12+8) cm

=>Perimeter=2(20) cm

=>Perimeter=40 cm

Answer:-

Length of the rectangle=12 cm

Perimeter of the rectangle=40 cm
