How can you change the dimensions of the rectangle so that the ratio of the length to the width stays the same, but the perimeter is 185 cm? Length is 25 cm and width is 12 cm

L = 62.5cm; B = 30cm

Step-by-step explanation:

P = 2 (L+W) : L=25cm; W=12cm

=2 (25+12)

=50+24

P = 74cm

For a congruent rectangle with P = 185cm

A: 74 = 2 (25 + 12)

B: 185 = 2 (? + ?)

Since A/B are congruent;

185/75 = 2.5

B = 2 (2.5 * (25 + 12)

= 2 (62.5 + 30)

= 125 + 60

= 185

Hence, B: L = 62.5cm; B = 30cm

185cm = 2 (62.5 + 30)
