Question

A rectangular frame has a length of 5 feet and a width of 4 feet. A similar rectangle has a width of 12 feet. What is the length of the rectangle

Answer

Let the length be 'x'

$length \: \: \: \: \: \: breadth$

$5 \: \: \: \: \: \: \: \: \: \: \: \: 4$

$x \: \: \: \: \: \: \: \: \: 12$

Cross multiplication

$\frac{5 \times 12}{4 \times x} = \frac{60}{4x}$

$x = \frac{60}{4} = 15$

Hence the length of similar triangle is 15 cm
