the length of a rectangle is four times as long as it's width. the perimeter of the rectangle is 50cm. find it's length​

Step-by-step explanation:

let the width be x and length be 4x , as it is 4 times more than width

given,

perimeter = 50 cm

we know,

perimeter = 2l + 2b/w

so,

2l + 2b = 50

after inserting the values we got,

→ 2(4x) + 2(x) = 50

→ 8x + 2x = 50

→ 10x = 50

→ x = 50/10 = 5

→ x = 5

therefore, length = 4x = 4×5 = 20 cm

hope this answer helps you deartake care and may u have a great day ahead!
