Question

use the correct number of significant digits to write the are a d perimeter of the yard. the length of the yard is 18 and width is 13.8 ( round answer to least precise measurement) 1. what is the permiter of the yard2. what is the area of the yard

Answer 1

The perimeter is given by the following formula:

P = 2w + 2l

Where:

w = width = 13.8

l = length = 18

So:

P = 2*18 + 2*13.8 = 63.6

The area is:

A = w*l

A = 13.8*18 =248.4
