Recall

Areas and perimeters of plane figures — objective 1

Maths4U Original · Short practice

A rectangle has length 10 cm and width 2 cm. Separately, a triangle and a parallelogram each have base 10 cm and perpendicular height 4 cm. A trapezium has parallel sides 10 cm and 12 cm and perpendicular height 4 cm.

Find the rectangle perimeter in cm.

Enter one exact number or fraction unless the question specifies rounding. If it asks for a coefficient of π, enter that coefficient only. Give full reasoning separately for written problems.
