Question

A rectangle has a height of 8 inches and a base of 12 inches. If we double the height, by how many inches will the perimeter increase?

Answer 1

Perimeter is the total sum of the 4 sides.

The height is given as 8 inches. If this is doubled the new height becomes 16 inches. (The height increases by 8 inches)

total increase in perimeter = 8 + 8 = 16 inches.

Answer: 16 inches
