Question

The length of a rectangle exceeds its width by 8cm and the area of the rectangle is 240 sq. Cm find tge dimenshions of the rectangle?

Answer 1

Answer:

Step-by-step explanation:

Let the breadth be x

so the length will be x+8

area of the rectangle=240cm²

∵area of rectangle=length*breadth

∴240=(x)(x+8)

240=x²+8x

x²+8x-240=0

x²+20x-12x-240=0

x(x+20)-12(x+20)=0

(x+20)(x-12)=0

so x=-20 or x=12

∵The dimensions cannot be negative

∴x=12

length=20cm

breadth=12cm
