Question

A rectangle has a length of 3x and a width of x . If the perimeter of the rectangle is 48 cm, what are the dimensions of the rectangle? *

Answer 1

perimeter of a triangle is the total

Explanation:

p=48cm

Length=3x

width=x

Now P= 2(L+W)

48 =2(3x+x)

48=2(4x)

48=8x

dividing both sides by 8

we have x=6

and so length=18 and width =6
