Answer 1

Answer:

WE KNOW THAT PEMIETER IS 32

LENGTH AND BREADTH WILL COMBINE AND MAKE UP TO = 16

LENGTH = 12 BREADTH = 4

12 × 4 = ANSWER

= 48

YOUR ANSWER IS 48

Answer 2

Given :-

• Length of Rectangle is thrice of it's breadth.
• Perimeter of Rectangle = 32 cm.

To Find :-

• Area of Rectangle ?

Solution :-

• Let the breadth of rectangle be y.
• As it is stated that length of rectangle is thrice of its breadth so length of rectangle will be 3y.

Using formula,

• Perimeter of rectangle = 2(l + b)

Where,

• l denotes length of rectangle
• b denotes breadth of rectangle

We have,

• Length of rectangle (l) = 3y
• Breadth of rectangle (b) = y
• Perimeter of rectangle = 32 cm

• Putting all values in formula,

➻ 32 = 2(3y + y)

➻ 32 = 2(4y)

➻ 32 = 2 × 4y

➻ 32 = 8y

➻ 8y = 32

➻ y = 32/8

➻ y = 4

Using formula,

• Area of rectangle = l × b

Where,

• l denotes length of rectangle
• b denotes breadth of rectangle

We have,

• Length of rectangle (l) = 3y
• Breadth of rectangle (b) = y

• Putting all values in formula,

➻ Area of rectangle = 3y × y

➻ Area of rectangle = 3 × y × y

➻ Area of rectangle = 3 × y²

• Putting values of y,

➻ Area of rectangle = 3 × 4²

➻ Area of rectangle = 3 × 4 × 4

➻ Area of rectangle = 12 × 4

➻ Area of rectangle = 48 cm²

• Hence, area of rectangle is 48 cm².
