The area of a rectangle is given by:
`A = bh`
where A is the area, b = base length and h is the height.
A rectangle that is 8 units along its base length, and 4 units high, has an area of 32 units square.
Note that the area units are squared: for example, a rectangle of 5 cm x 3 cm has an area of 15 cm2
1. What is the area of a rectangle with a base length of 15.5 cm and a height of 4 cm?
Answer: 62 cm2
Area = base x height = 15.5 x 4. Remember the answer is in cm2
2. One side of a rectangular building is completely covered in glass. The area of the glass is 550 m2. If the building is 55m long, how tall is the building?
Area = base x height
550 = 55 x h
h = 10
