Answer:
Breadth: 45 cm.
Area: 3,150 cm^2.
Explanation:
The perimeter is 230. Since the length of the rectangle is 70 cm, and 70 * 2 = 140, the sum of the two breadths will be 230 - 140 = 90. That means that the breadth is 90 / 2 = 45 cm.
If the breadth is 45, and the length is 70, then the area is 45 * 70 = 3,150 cm^2.
Hope this helps!
