Answer:
50=2(10+w)
Explanation:
We know that perimeter is equal to the sides of a shape
A rectangle has two of the same length and two of the same width
P=2l+2w
We know the perimeter and length so plug that in and solve for w
50=2(10)+2w
50=2(10+w) - That matches answer choice D
30=2w
w=15
Equation: 2 (w + 10) = 50
Equation of the perimeter of a rectangle:
=> 2 ( w + l) = P where w= width, l = length, and P = perimeter
Substitute the given values:
=> 2 ( w + 10) = 50
There you have it!
Hope this helps!
