Question

DEFG ,L= 40 cm ,perimeters =110cm so, what will breadth and area of rectangle ​

Answer 1

Answer:

Subtract length from perimeter , then take out it's area

Step-by-step explanation:

P=110cm L=40cm B=?

P of rectangle = 2 x L + B

B = P - L

= 110 - 40cm

= 90cm

A of rectangle = L x B

= 40 x 90cm

= 360cm2

Answer 2

Answer:

Breadth=15, Area=600cm^2

Step-by-step explanation:

We know,

Length= 40cm

Perimeter= 110cm

Let Breadth be 'b'

Perimeter= 2(length+breadth)

=>110=2(40+b)

=>110=80+2b

=>110-80=2b

=>30=2b

=>30/2=b =>15=b

• Breadth=b=15cm
• Area= length*breadth

=>40*15

=600cm^2

Hope it helps...
