Question

5. What is the area, in centimeters square, of a rectangle whose width is twice its length

and whose length is 7 centimeters?
A. 42 cm2
B. 98 cm2
C. 147 cm
D.
196 cm2

Answer 1

if the length is 7cm, you multiply it by 2 because it’s “twice it’s length”.
7x2 = 14
the width is 14cm.
area of a rectangle = LxW
14x7 = 98

The area of the rectangle is 98cm2
The answer is B
