Question

08. The length of a rectangle is 3 times its width. The perimeter of the rectangle
120cm. Find the dimensions of the rectangle​

Answer 1

Answer:

I hope it helps and that my handwriting is legible.

Step-by-step explanation:

Dimensions of the rectangle :

length= 3x

width= x

perimeter = 120cm

perimeter of rectangle = 2(l+b)

Hence,

2(l+b) = perimeter

2(3x+x) = 120

2(4x) = 120

8x = 120

x = 120/8

x = 15 cm

breadth = x = 15cm

length = 3 * x = 15*3 = 45 cm

breadth= 15cm

length= 45cm
