P = 2l + 2w
l = 2w + 8
P = 136
136 = 2l + 2w
136 = 2(2w+8) + 2w
136 = 4w + 16 + 2w
136 = 6w + 16
120 = 6w
w = 20
l = 2(20) + 8
l = 40 + 8
l = 48

CHECK:
136 = 2l + 2w
136 = 2(48) + 2(20)
136 = 96 + 40
136 = 136

How does increasing the dimensions of a rectangle impact the perimeter?

If you increase the rectangle's length by a value, its perimeter increases by twice that value. If you increase the rectangle's width by a value, its perimeter increases by twice that value. (A rectangle is defined by its length and width, and opposite sides of a rectangle are the same length. The lines always meet at their endpoints at 90° angles.)


The length of a rectangle is 5 cm more than twice the width The perimeter of the rectanle is 34 cm find the dimensions of the rectangle?

4cm by 13cm


When The width of a rectangle is 3 more than twice its length. The perimeter is 60 feet. Find the width and length of the rectangle.?

The dimensions of the rectangle are 21 units by 9 units


Can 2 rectangles with the same area have different perimeters?

Yes, two rectangles can have the same area but different perimeters. The area of a rectangle is calculated by multiplying its length and width, while the perimeter is calculated by adding twice the length and twice the width. For example, a rectangle with dimensions 2x6 has an area of 12 and a perimeter of 16, while a rectangle with dimensions 3x4 also has an area of 12 but a perimeter of 14.


Can you draw a shape that the perimeter is numerically twice the area?

Yes, a shape can be drawn where the perimeter is numerically twice the area. A classic example is a rectangle with dimensions 2 units by 1 unit. The perimeter of this rectangle is 2(2 + 1) = 6 units, while the area is 2 × 1 = 2 square units. Here, the perimeter (6) is indeed twice the area (2).

What is the perimeter of a rectangle with length 42 inches?

A rectangle has two dimensions, length and width. You haven't said what the width is. The perimeter is the distance around the rectangle. Imagine going round it. You would go 42 inches, then a width, then another 42 inches, then another width. In general, the perimeter of a rectangle is twice its length plus twice its width.

The length of a rectangle is twice the width width the perimeter is 48 in find the dimensions of the rectangle?

Let the width of the rectangle be represented by "w" inches. Since the length is twice the width, it can be expressed as "2w" inches. The formula for the perimeter of a rectangle is P = 2(l + w), where P is the perimeter, l is the length, and w is the width. Substituting the given values into the formula, we get 48 = 2(2w + w). Simplifying, we find that 48 = 6w. Solving for w, we find that the width of the rectangle is 8 inches, and the length is 16 inches.
