How does doubling the each dimension of a rectangle that is not a square affect the perimeter and the area of that rectangle?
quadruples it
What is the area of the rectangle if the radius of each circle is 6cm?
It depends on the relationship between the rectangle and the circles.
How many time does a 4 by 5 rectangle go into a 40 by 120 rectangle?
240 times. We need to find the area of each and divide them into each other. Rectangle 1: 4x5=20 Rectangle 2: 40x120=4800 The area of cube 2 divided my the area of cube 1 is the answer. 4800/20=240.
What kind of operation do you need to calculate the are of a rectangle?
MULTIPLICATION area for a rectangle is A = L * W * H where, A = area of rectangle L = Length of rectangle W = width of rectangle H = height of rectangle The dimensions of a rectangle (L, W, and H) are interchangeable because they are being multiplied together and hence each side of the rectangle can be arbitrarily assigned to a dimension.
Can you explain why the area of a triangle is 1 half base height while the area rectangle or a parallelogram is expressed as base height?
If you draw a diagonal in a rectangle you get two equal triangles, each half the area of the rectangle. Area of rectangle is base x height, so half of that is ½ x base x height. QED
