48/4=12
10+10+14+14=48
Ответ:
Length = L = 14 ft
P = perimeter = 48 ft
Explanation:
P rectangle = 2L+ 2W
L = W + 4
P = 48
Substitute into formula:
P rectangle = 2L + 2W
48 = 2( W + 4 ) + 2W
48 = 2W + 8 + 2 W
48= 4W + 8
48 - 8 = 4W
40 = 4W
W = 40/4 = 10
W = 10
The rectangle has a length that is 4 ft more than its width : L = W + 4
Substitute : L = 10 + 4 = 14
L = 14 ft
I hope this help!!!
