Question

The perimeter of a rectangular solar panel is 540 cm. The ratio of the length to the width is 3 : 2. What are the length and width?

Answer 1

Total number of parts = 3 + 2 = 5 parts

$each \: part \: = \frac{(540 \div 5)}{2} \: m$

$\\ each \: part \: = \frac{108}{2} m \: \\ \\ each \: part \: = 54 \: m$

Then , the length of this triangle :

$54 \times 3 \: m$

$= 162 \: m$

Then , the width of this triangle will be :

$54 \times 2 \: m$

$108 \: m$

∴ The length of this rectangle is 162 m and the width of this rectangle is 108 m .
