Question

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

Answer 1

Answer:

78cm

Step-by-step explanation:

area of the rectangle = 290cm*

l × b = 290cm*

(2 × -5) × b = 290cm*

b = -290cm* ÷ 10

b = - 29cm

perimeter = 2( l + b)

= 2( -10cm + ( - 29cm ) )

= 2( - 39cm )

= -78cm
