Question

Ali says that the perimeter of the rectangle on the coordinate plane is equal to 30 units , choose the correct answer that shows Ali's mistake ?

Answer 1

Hello!

P= 6+5+6+5 =22u

or

2(6+5) = 2*11 => 22u

6*5 = 30 is area

Answer 2

Explanation:

I don't see answer options, but I can very well guess what went wrong :

he used the area formula to calculate the perimeter.

the area would be length × width, in our case

6 × 5 = 30 units²

but the perimeter is 2×length + 2×width, in our case

2×6 + 2×5 = 12 + 10 = 22 units
