Question

The perimeter of a rectangular painting is 294 centimeters. If the width of the painting is 62 centimeters, what is its length?

Answer 1

Answer: 85

Explanation:

If the perimeter is 294 centimeters, and the width is 62 cm, we can put that in the perimeter formula. 2l x 2w = P

2l x 62(2) = 294

62 * 2 is equal to 124.

We can subtract 124 from 294 to get 2 x l.

294 - 124 = 170.

This means that 2 x l = 170

So to get the length we have to divide 170 by 2.

170/2 is 85.

So the length is 85 cm.
