The area of a rectangle is measured by base times height:
A = bh
If both dimensions are cut in half, we are left with:
(0.5b)(0.5h) = 0.25bh
This is one-fourth of the original area.
A = bh
If both dimensions are cut in half, we are left with:
(0.5b)(0.5h) = 0.25bh
This is one-fourth of the original area.
Area = base * height = 35 square inches
When we make the dimensions 2.5 by 3.5 then,area = 2.5 * 3.5 = 8.75 square inches
35 / 8.75 = 4So, when we reduce the width AND the height by 2, the area decreases by 4.Why? Because when we are reducing 2 dimensions:area = width/ 2 * length / 2 = area / 4
