The perimeter is the sum of the sides. Let's call the width length w so the length l is w+7
58 = w + w+7 + w + w+7 = 4w+14
44 = 4w
w = 11
l = w + 7 = 18
Answer: Length 18 width 11
Answer:
Step-by-step explanation:
(W+7) equal length
W EQUALS WIDTH
So 2L+2W = perimeter = 58
Substitute length and we get
2(w+7)+ (2w) = 58
2w+14+ 2w = 58
4w+ 14 = 58
4w = 58-14 = 44
Divide each side by 4
4w/4 = 44/4
4/4=1 therefore x=11
Test answer
2(11+7) + 2(11) = perimeter
22+14+22= 58
