Mathematical Reasoning第 35 / 120 题
A rectangle has a length of 12 cm and a width of 5 cm. What is its area?
a.17 cm²
b.34 cm²
c.60 cm²
d.120 cm²
解析
Area of a rectangle is length times width: 12 × 5 = 60 square centimeters. Area is always expressed in square units. The perimeter, by contrast, would be 2(12 + 5) = 34 cm.
