Question

perimeter of rectangle is 360 cm. if the ratio of the length to its width is 11 ratio 4 find the dimension off rectangle

Answer 1

Step-by-step explanation:

Let the length of rectangle be 'L'

Let the width of rectangle be 'B'

2(L+B)=360cm

L+B=180cm-------(equation 1)

(L/B)=(11/4)

4L=11B------(equation 2)

Multiplying equation 1 with 4

4(L+B)=720

4L+4B=720-----(equation 3)

putting value of equation 2 in equation 3

11B+4B=720

15B=720

B=48cm

putting B=48cm in equation 2

L=(11/4)(48)

L=132cm

therefore, Length is '132cm'

therefore, Breadth is '48cm'
