Question

the perimeter of a rectangle is window is 304 cm. if the width of the window is 68 cm, what is it length?

Answer 1

84 cm

Explanation:

This is the answer because:

1) We know that the width of the window is 68 cm

2) Since the width of the window is 68 cm, we should add 68 and 68 because then we would know half of our length because it's a rectangle.

68 + 68 = 136

3) After, just subtract 304 - 136

304 - 136 = 168

4) Finally, just divide 168/2

168/2 = 84

Therefore, the length is 84 cm long

Hope this helps!

Answer 2

The length is 85 cm

Explanation:

the length is 85cm. this is because the total perimeter of the rectangle is 304 cm and the width of it is 68 cm so you add 68 + 68 because there's two sides for the woods and you get 136. so the width for both sides of the width is 136 so you take 304 - 136 and you get a 170. The 170 is the total length from both sides . so to find just the regular for one side you do 170 / 2 and you get 85 .
