Question

Q:5 The length of a rectangle is four times its breadth.If the perimeter is 45m find the length of the
rectangle.​

Answer 1

Answer:

18m

Step-by-step explanation:

Let the breadth of rect. be x

:- Length = 4x

A. T. Q :-

we know,

perimeter of the rectangle = 45m

2 { l + b } = 45 m

2 { 4x + x } = 45 m

2 { 5x } = 45 m

10x = 45 m

x = 45 m / 10

x = 4.5 m

:- breadth =x =4.5 m

:- length = 4x

= 4 × 4.5 m

= 18 m

so,the required length of rectangle is 18m
