Question

In Figure, ABCD is a rectangle, with AB=(2x - 5)cm and BC = (x + 2)cm. The area of the rectangle is 290 cm². Calculate the perimeter, in cm, of the rectangle.​

Answer 1

the perimeter of rectangle is

(LxB)

(ABxBC)

(2x-5xX+2)

(2x-X x 5+2)

(X x 3)

(3x)

the perimeter is

290=3x

290/3=x

96.6=x

cm2=48.3x48.3

=96.6
