Answer:
<h2>The answer is 8 ft</h2>
Step-by-step explanation:
Perimeter of a rectangle = 2l + 2w
where
l is the length
w is the width
From the question
perimeter = 40 ft
length = 12 ft
Substitute the values into the above formula and solve for the width
That's
40 = 2(12) + 2w
40 = 24 + 2w
2w = 40 - 24
2w = 16
Divide both sides by 2
We have the final answer as
<h3>8 ft</h3>
Hope this helps you
Add these eqn and then you have to cancel out (y) after that add x and 2x which is equal to 3x and also add RHS i.e.30 and divide it by 3
