Question

2. The perimeter of a rectangle is 32 cm and its length is 10 cm. Find its breadth and area​

Answer 1

Answer:

let breadth if the rectangle is b cm

so, 2(length+breadth)= perimeter

=> 2(10+b)=32

=> 10+b=32/2=16

=> b=16-10=6

so breath of the rectangle is 6 cm

area of the rectangle is length×breadth

=10×6sq cm

=60sq cm

Answer 2

Answer:

= x = 6  

Breadth = 6 centimeter

Step-by-step explanation:

Perimeter = 32 cm

length = 10 cm

breadth = ?

Let the breadth be x

Breadth =  (10 + x)*2 = 32

= 20 + 2x = 32

= 32 - 20 = 2x

= 12 = 2x

= 2x = 12

= x = 12/2

= x = 6
