Answer:
<h2>Length = 13 in.
</h2>
Step-by-step explanation:
perimeter of a rectangle (P) = 2L + 2W
where;
P = 42 in.
Length (L) = 5 + W
Find:
length (L) of the rectangle
solution:
P = 2L + 2W
42 = 2(5 + W) + 2W
42 = 10 + 2W + 2W
42 - 10 = 4W
32 = 4W
W = 32/4
W = 8
Length (L) = 5 + W
= 5 + 8
= 13 in
proof:
42 = 2(13) + 2(8)
42 = 42 in
