when keisha installed a fence along the 200 feet perimeter of her rectangular back yard she left and opening for GATE in diagram below she used X to represent the length of the gate (I give brainliest)

(x + 60 + 30) * 2 = 200

(x + 90) * 2 = 200 multiply 2 inside parentheses

2x + 180 = 200 move 180 to the other side with changing it's sign

2x = 20 multiply by 2

x = 10 here is the answer

Step-by-step explanation:

Perimeter = (length + width) * 2

Hope this helps.
