Question

Kirby drew a quadrilateral with four right angles, a side that measures 9 centimeters, and a side that measures 6 centimeters. What is the figure? What is its perimeter

Answer 1

the figure is a rectangle and the perimeter would be 30 because 9+9+6+6=30

Answer 2

Perimeter of the rectangle is 30 cm.

Explanation:

Kirby drew a quadrilateral with 4 right angles, a side that measures 9 centimeters and a side that measure 6 centimeters.

Since quadrilateral has all its sides equal to 90° and opposite side equal in size.

Therefore, the quadrilateral is a rectangle.

Perimeter of rectangle = sum of all sides

= [ 9 + 9 ] + [ 6 + 6 ]

= [ 18 ] + [ 12 ]

= 30

Perimeter of the rectangle is 30 cm.
