The length of a rectangle is4 times its width the perimeter of the rectangle I'd 150cm find the dimension of the rectangle by using matrix inversion method

$\huge\tt\colorbox{Purple}{Solution }$

Let L be length of rectangle

Let B be width of rectangle

Perimeter of Rectangle given is 150cm

ie 2L+2B=150Cm

Also L=4B given data

Hence 2x4B+2B=150

10B=150CM

Hence B=15cm and L=60cm
