Question

The length of a rectangler picture is 5 inches more than three times the width find the dimensions of the picture if its perimeter is 74 inches

Answer 1

Answer:

Length = 29 inches

width = 8 inches

Step-by-step explanation:

perimeter of a rectangle= p =2*L+2*w

L= Length

w = width

we have from the statement:

L= 5+3*w

p=74

so we have:

74 =2*(5+3*w)+2*w

74= 10+ 6w +2w

74-10=8w

64=8w

w = 64/8

w =8 inches = width

so L= 5+3*(8)

L= 5+24

L= 29 inches = Length
