Yes because 0 and 4 dont equal 10 and 20 and 40 dont equal 100. So no and 40 + 23 = 63.

Yes because when you add, there's nothing to carry. 23 plus 40 equals 63.

4 - The area of a rectangle is 256.5m. If the length is 18m what is the perimeter of the rectangle? -
attashe74 [19]
The equation of the area of a triangle is Area=Length×Width. We know area=256.5 and length is 18. So now we know 256.5=18×width. We then divide 256.5÷18 to get the width. The width is 14.25. Perimeter=legth+length+width+width. If width is 18 and length is 14.25 then we add up all 4 sides. 18+18+14.25+14.25=64.5. 64.5 is the perimeter
