GenaCL600 [577]

Answer:

24ft

Step-by-step explanation:

Pythagorean Theorem!!

a^2 + b^2 = c^2

------------------------

In this case, the ladder is c, and the base is b.

------------------------

Plug the numbers in the formula.

a^2 + 7^2 = 25^2

------------------------

Solve.

a^2 + 49 = 625

a^2 -49 = 625 - 49

a^2 = 576

\sqrt{a^2} = \sqrt{576}

a = 24

Can someone please help?!!!
Nuetrik [128]

The perimeter of a rectangle is P=2l+2w where l is the length and w is the width.

Plug in values of l and w in:

P=2(x+8)+2(x-1)

P=2x+16+2x-2

P=4x+14

So the perimeter of the rectangle is 4x+14 units

Hope this helped!
