Answer:

Step-by-step explanation:

The square means a $90$ degree angle.

We know that all the angles in a triangle add to $180$ degrees. So, we can build an equation for x: $(2x+1)+(5x+5)+(90)=180$

Combining like terms on the left side gives $7x+96=180$

Subtracting $96$ from both sides gives $7x=84$

Dividing both sides by $7$ gives $\boxed{x=12}$

You may remember that the perimeter of a rectangle is P=2(W+L) where W is the width and L is the length. Suppose that the perime

Anna71 [15]

Answer:

5 feet

Step-by-step explanation:

P = 2(w + l)

P = 34

l = w + 7

34 = 2 (w + w + 7)

34 = 2w + 2w + 14

34 - 14 = 4w

20 = 4w

w = 5 feet

Since l = w + 7

l = 5 + 7

l = 12 feet
