Question

The length of a rectangle is 3 centimeters more than 3 times the width. If the perimeter of the rectangle is 46 centimeters, find the dimensions of the rectangle. length = 18 cm; width = 5 cm length = 5 cm; width = 18 cm length = 13 cm; width = 8 cm length = 13 cm; width = 5 cm

Answer 1

Answer:

Length=18 cm

&, width=5 cm

Explanation:

Let,

length of rectangle= L

width of rectangle= W

Then according to question,

length = 3cm more than 3 times width

L= 3 + 3×W

L= 3 + 3W➡ Eqn(1)

Also,

perimeter=2×(length + width)

46= 2L+2W

46=2×(3+3W)+2W➡eqn(1) is used

46-6=8W

40=8W

W=5 cm

Thus,from above eqn,

L=3+3×5

L=18 cm
