Question

the perimeter of a rectangle is 72 CM the length is 3 times the width find the area of the rectangle​

Answer 1

Answer:

let the width be x

the length = 3x

perimeter = 72

3x + x = 72

4x =72

x = 72/4

x =18

so the breadth is 18 and length is 54

now you can calculate

PLEASE MAKE IT AS BRAIN LIEST ANSWER

Answer 2

Answer:

Let the breadth of rectangle be x

the length of rectangle=3x

Perimeter of rectangle=2(l+b)

72=2(x+3x)

72/2=4x

36=4x

36/4=x

9=x

Breadth of rectangle = 9cm

Length of rectangle=3x=3(9)=27cm
