If a rectangle has a perimeter of 56 inches and a width of 8 inches, what is the area

160 inches

Step-by-step explanation:

Area = L times W

In a rectangle, there are 4 sides

2 are width

2 are length

56 is total

8 + 8 = 16

56 - 16 = 40

40 is what is left for the 2 length sides

since there are 2 sides and they need to be equal, we divided 40 by 2

40 / 2 = 20

the length of one side is 20

area = 8 times 20

a = 160 inches

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
