Question

Keala is making a new book cover before giving their favorite picture book to their little brother. The cover is 22 1/4 tall. It has a rectangular shape and an area of 890 cm2.

How wide across is Keala's book cover?

Answer 1

40 cm

Explanation:

For a rectangle,

area = length × width

width = area/length

area = 890 cm²

length = 22.25 cm

length = (890 cm²)/(22.25 cm)

length = 40 cm
