This is solved by simultaneous equations. Perimeter = 2a + 2b = 100 where a and b are lengths of sides Area = a x b Rearranging the perimeter equation: 2a = 100 - 2b, a = 50 - b Putting this equation into the area equation: Area = (50 - b) x b = 50b - b x b Find the minimum/maximum by differentiating and setting to 0. Area' = 50 - 2b = 0, 2b = 50, b = 25 Area = 625cm sqare. when the length tends to 50, the area tends to 0. So the area can be anything from 0 to 625 cm

What could the perimeter of a rectangle be if the area is 22cm2?
26 cm
The area of a rectangle is 100 inches the perimeter is 40 a second rectangle has the same area but a different perimeter. Is the second rectangle a square?
the area of a rectangleis 100 square inches. The perimeter of the rectangle is 40 inches. A second rectangle has the same area but a different perimeter. Is the secind rectangle a square? Explain why or why not.
What is the perimeter of a rectangle has an area of 5cm square?
The perimeter of a rectangle cannot be determined with the area alone as the lengths could vary. For example, the perimeter of the rectangle could be 12 (1 and 5) or 9 (2 and 2.5). For both cases, the area is still 5cm2, but the length can still change to result in different results.
A rectangle with the same area and perimeter?
Would be congruent.It doesn't have to be a rectangle, though.It could be any shape.
If same area in a rectangle does that mean same perimeter?
No. For example, a 4x1 rectangle will have an area of 4 and a perimeter of 10. A 2x2 rectangle will have the same area of 4, but a perimeter of 8.
What could the perimeter of a rectangle be if the area is 22cm2?
26 cm
What is a perimeter of a square whose area is 625cm square?
The perimeter is 100cm

The length of a rectangle is twice its width If the perimeter of the rectangle is 54y find its area?
The length of a rectangle is twice its width. If the perimeter of the rectangle is , find its area.
What is the perimeter of a rectangle with an area of 24cm?
The perimeter of the rectangle is the sum of its 4 sides.
How can you find the answer for the perimeter and area of a rectangle?
find the perimeter and area of a rectangle that is 15cm long and 5cm wide
What is the effect on the perimeter of a rectangle if the dimension are doubled what is the effect on its area?
Let's take a look at this problem.Rectangle Perimeter = 2(l + w)Rectangle Perimeter =? 2(2l + 2w)Rectangle Perimeter =? (2)(2)(l + w)2(Rectangle Perimeter) = 2[2(l + w)]Thus, we can say that the perimeter of a rectangle is doubled when its dimensions are doubled.Rectangle Area = lwRectangle Area =? (2l)(2w)Rectangle Area =? 4lw4(Rectangle Area) = 4lwThus, we can say that the area of a rectangle is quadruplicated when its dimensions are doubled.
The length of a rectangle is 5 more then the width Find the perimeter and the area of the rectangle?
the length of a rectangle is 5 more then the width. Find the perimeter and the area of the rectangle
How two parallelograms could have the same area but different perimeters?
yes, for example:a 4 by 5 rectangle has an area of 20 and a perimeter of 18a 2 by 7 rectangle has an area of 14 and a perimeter of 18yes, for example:
