Question

A room measures 15 ft by 12 ft . Sketch and label a diagram and then calculate its area and perimeter

Answer 1

For a rectangle,

area = length × width
perimeter = 2(length + width).

Example:
for a rectangle with
length = 5 ft
width = 3 ft
area = 5×3 = 15 square feet
perimeter = 2(5+3) = 16 feet
