Question

Find the perimeter of a rectangle whose width is 5c 2 and its length is 9c - 10

Answer 1

The perimeter of a rectangle with width 5c^2 and length 9c - 10 is 10c^2 + 18c - 20.

Step-by-step explanation:

To find the perimeter of a rectangle, we use the formula P = 2l + 2w, where P is the perimeter, l is the length, and w is the width. For a rectangle with width 5c2 and length 9c - 10, the perimeter would be calculated as follows:

P = 2(5c2) + 2(9c - 10)

First, multiply the width by 2:

2(5c2) = 10c2

Then, multiply the length by 2:

2(9c - 10) = 18c - 20

Add these results together to find the total perimeter:
P = 10c2 + 18c - 20

Therefore, the perimeter of the rectangle is 10c2 + 18c - 20.
