Question

Rectangle A has area 50 cm 2 and length 10 cm. The area of rectangle B is one-half the

area of rectangle A. The rectangles have the same length.
What is the width of rectangle B?

Answer 1

2.5

Explanation:

Area of A is 50 cm ^2

length of A is 10

Area of B is 50/2 cm^2 or 25cm^2

area for all rectangles is length * width

so area of B divided by length of b is width of b

25/10 = 2.5

width of b is 2.5
