Question

The length of a rectangle is three
times its width. It the perimeter of the
rectangle is 96m, find the length and
breadth of the rectangle.

Answer 1

Answer:width = 12 cm

length = 12*3= 36cm

Step-by-step explanation:

let the width be x

then length = 3x

perimeter = 96 cm

since, perimeter = 2(l+b)

2(3x+x)=96cm

6x+2x=96cm

8x=96cm

x=96/8= 12

ANS - width = 12 cm

length = 12*3= 36 cm

Answer 2

Answer:

let the breadth be x

let length be 3x

Given PERIMETER =96 M.

PERIMETER = 2 * ( L+B)

96 = 2*3X+X

96 = 2*4X

96 = 8x

8 x = 96

x = 96 /8

x= 12 (Breadth)

3x = 12*3 = 36 (length)

how to be confident here given PERIMETER is 96 so if we use 2×(36 +12);is 96
