Question

the width of a rectangleis three foirth its length if the perimeter is210m find the dimensions of the rectangle ​

Answer 1

Step-by-step explanation:

let the length be x m

width /breadth =3/4 of x

perimeter =210m

2(l+b)=210

2(x+3/4*x)=210

x+3x/4=210/2

(4x+3x)/4=105

7x=105*4

x=420/7

x=60

Length =60m

Width =3/4*60=3*15=45m

Hope it helps ✌✌

Answer 2

Answer:

Step-by-step explanation:

Let length be X then width will be 3/4X as perimeter is

2 (length + width)= 210 (1)

Putting length X and width 3/4X

Dividing two on both sides of equipment (1)

X+3/4X=210

7/3X=210

X=210×3/7

X=90 is the length and

3/4X=67.5 us the width
