Question

The shaded rectangle is twice long as it is wide. the perimeter of the rectangle is 30 cm.

Answer 1

10 cm

Explanation:

The perimeter of a rectangle is given by the formula P = 2(l + w), where P is the perimeter, l is the length and w is the width1. We know that the perimeter of this rectangle is 30 cm. So we can write:

2(2w + w) = 30

Simplifying this equation gives:

6w = 30

Therefore:

w = 5

So the width of the rectangle is 5 cm and its length is twice as long as its width which means it’s 10 cm.

Answer 2

Answer:Width=5, Length=10

Explanation:

You can solve this by using a variable, x, and assigning it to the value that is the width.

Since the perimeter of a rectangle is the width times two plus the length times two, you can use an equation that looks like this:

(image shown)

This will give you the value of X, the width, and you can multiply this value by 2 to get the length.
