Question

please answer
4. Find the breadth and perimeter of the rectangle if its area is 96 cm² and the length is 12 cm.
​

Answer 1

Answer:

Area=length*breadth

breadth=area/length

breadth=96/12=8cm

Perimeter=2(l+b)=2(12+8)=2*20=40cm

Answer 2

Answer:

Breadth = 8 cm

Perimeter = 40cm

Step-by-step explanation:

Area of the rectangle = 96 cm²

Length = 12 cm

Breadth = $\frac{area}{length}$

=$\frac{96}{12}$

= 8

Therefore, Breadth = 8 cm

Perimeter = 2 × ( L + B )

= 2 × ( 12 + 8 )

= 2 × 20

= 40 cm

Therefore, perimeter = 40 cm
