Question

The perimeter of a poster is 10 feet. The poster is 3 feet tall. How wide is it

Answer 1

The poster is 2 feet wide.

Explanation:

"Perimeter" is the distance all the way around a shape. To find perimeter you add up all the sides.

Here, we know the perimeter is 10 feet.

P = L + W + L + W

or

P = 2L + 2W

fill in what we know.

10 = 2(3) + 2W

10 = 6 + 2W

subtract 6

4 = 2W

divide by 2

2 = W

The poster is 2 feet wide.
