How can you change the dimensions of the rectangle so that the ratio of the length to the width stays the same, but the perimete
r is 185 cm? Length is 25 cm and width is 12 cm
1 answer:
Answer:
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)
