Question

Length of rectangle is 16cm. less than twice its breadth of perimeter of rectangle is 100 cm. Find its length​

Answer 1

Answer:

length = 28

breath=22

Step-by-step explanation:

let the breath of rectangle =x

let the length of rectangle = 16–2x

perimeter of rectangle =100

$2(l + b) = perimeter \\ 2( x+ 2x - 16 ) = 100 \\ 2x + 4x - 32 = 100 \\ 6x = 100 + 32 \\ 6x = 132 \\ x = 22cm$

$lenght = 2x - 16 \\ 2 \times 22 - 16 = 44 - 16 \\ = 28cm$
