Question

The length and the width of a rectangle are in ratio 3 : 7. The perimeter is 260 cm. Find the dimensions of the rectangle.

Answer 1

Answer ⬇️

Let x represent the constant of proportionality

2(3x) + 2(7x) = 260cm

20x = 260cm

x = 13cm

L = 3(13cm)

w = 7(13cm)

____________________

checking

2(3x) + 2(7x) = 260cm

78cm + 182cm = 260cm
