The maximum area for a rectangle of fixed perimeter is that of the square that can be formed with the given perimeter. 136/4 = 34, so that the side of such a square will be 34 and its area 342 = 1156.

find the perimeter and area of a rectangle that is 15cm long and 5cm wide
The length of a rectangle is twice its width. If the perimeter of the rectangle is , find 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
100 cm2
That depends on the rectangle! You can have different rectangles with the same area, but with different perimeters.
Perimeter is a unit of length. Area is a unit of area. The two units are not directly convertible.However, the area of a rectangle is length times width, and the perimeter is two times length plus two times width. Given constant perimeter, a square has maximum area, while a very thin rectangle has nearly zero area. (In calculus terms, the limit of the area as length or width goes to zero is zero.)Depending on how you want to name your units, you can always find a rectangle whose perimeter is "larger" than area, but this is a numerical trick that is not valid in any school of thought of mathematics that I know.

A square of side 22 has an area of 484. Rectangle 23 x 21 has an area of 483...
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.
The perimeter of the rectangle is the sum of its 4 sides.
that's easy.....it's 1 ;)
find the perimeter and area of a rectangle that is 15cm long and 5cm wide
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.
If it was a square, the answer would be 81 square cm. The area will be the product of two numbers whose sum is half the perimeter.
The length of a rectangle is twice its width. If the perimeter of the rectangle is , find its area.
