the length of a rectangle is three more than the witch of the perimeter is 90 cm then find the dimensions

24 cm, 21 cm

Step-by-step explanation:

Let the width of the rectangle be x cm

So, length = x + 3 cm

Perimeter of rectangle = 90

2(x + 3 + x) = 90

(2x +3) = 90/2

2x + 3 = 45

2x = 45 - 3

2x = 42

x = 42/2

x = 21 cm

x + 3 = 21 + 3 = 24 cm

Length = 24 cm

Width = 21 cm

Hence, dimensions of the rectangle are 24 cm and 21 cm.

step-by-step explanation:

i found the koficent of the linear function and i foun c acordind to the strict formula y=kx+c and then i took 2 as an x and replacet it on the formula i found and then foun the y
