Question

. The length of a rectangle is 3 more than its width. If the perimeter of the
rectangle is 30 cm then find the length and width of the rectangle ?​

Answer 1

If the perimeter of the rectangle is 30 cm then find the length and width of the rectangle ? 1. See answer

Let width be x and length will be x +3 Perimeter = 2(l + b) 30=2(x +x+3)30 =2*(2x +3)30=4x +630-6=4x24=4xx=24/4Width=6Length =6+3=9 

Answer 2

Step-by-step explanation:

width= x

length=x+3

perimeter of rectangle=30

formula for perimeter

$2(l + b) \\ 2(x + x + 3) = 30 \\ 2(2x + 3) = 30 \\ 4x + 6 = 30 \\ 4x = 30 - 6 \\ 4x = 24 \\ x = \frac{24}{4} \\ x = 6$

l=6+3=9

b=6
