Question

A rectangle is 3 cm long and 2 cm wide

A. What is the perimeter of the rectangle in millimeters

B. What is the area of the rectangle in centimeters

Answer 1

Perimeter = 100mm

Area = 60mm

Explanation:

P= (3x2) + (2x2) =10cm

10mm to 1cm

10cm x 10 = 100mm

A= b x h

= 3 x 2

=6cm

6x10=60mm
