Question

Plz help I dont understand

Answer 1

Answer:

50=2(10+w)

Step-by-step 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

Answer 2

Answer:

Equation: 2 (w + 10) = 50

Step-by-step explanation:

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!
