Question

If the length of rectangle is 9 cm and area is 18cm find the breadth and perimeter.

Answer 1

Step-by-step explanation:

Area of the rectangle =lb=18cm²

Length of the rectangle =l=9cm

Breadth of the rectangle =Area/Length=18/9=2cm

Perimeter of the recrangle=2(l+b)=2(9+2)=2×11=22cm

Answer 2

Answer:

Breath of rectangle is 2 cm .

Perimeter of rectangle is 22 cm .

Step-by-step explanation:

Given -

Area of a rectangle = $18\:cm$

Length of rectangle = $9\: cm$

To find -

Breadth of rectangle

Perimeter of rectangle

Solution -

As we know that

Area of a rectangle = $W\:L$

Where,

W = Breath of rectangle

L = Length of rectangle

Put the given value in these formula

$18 = W \times 9$

Divide both side by 9 we get

$W = 2\: cm$

Perimeter of rectangle = $2(L+W)$

Perimeter of rectangle = $2 (9+ 2)$

Perimeter of rectangle = = $2 \times 11$

Perimeter of rectangle = $22 \: cm$

∴ Breath of rectangle is 2 cm .

Perimeter of rectangle is 22 cm .
