Question

Doug says the area of the figure is 20 square units. What is the correct area of

the figure? What mistake might Doug have made?
5 units
5 units

Answer 1

The correct area is 25 square units.

His mistake was that he found the perimeter instead of the area.

Explanation:

Area = Length x Width

Area= 5 x 5= 25

His mistake:

Perimeter = length + length + width + width

Perimeter = 5 + 5+ 5+ 5 = 20
