Question

The perimeter of rectangle ABCD is 56 , and if the length of AD = 16, what is the area of ABCD?

Answer 1

Area of the Rectangle`=192`

Explanation:

Perimeter of the rectangle `=2(a+b)` where `a=16` and `b=?`

or

Perimeter of the rectangle `56=2(16+b)`

or

`16+b=56/2`

or

`16+b=28`

or

`b=28-16`

or

`b=12`

Therefore Area of the Rectangle`=ab=16times12=192`
