Question

find the length of the rectangle whose perimeter is 74cm and breath is 12cm​

Answer 1

perimeter =74cm

breadth=12cm

let the Length be l

we know perimeter =2(length+breadth)

According to the question

$2(l+12)=74$

$=>2l+24=74$

$=>2l=74-24$

$=>2l=50$

$= > l = \frac{50}{2} \\ \\ = > l = 25$

Hence Length of the rectangle is 25cm

Answer 2

25 is the answer
