Question
In the following figure, the area of the total cloth required is 80 cm2 and the area of the yellow cloth required is 60 cm2. If the red colored parts are congruent to each other and the blue cloth is 110th of the yellow cloth, what is the area of the red cloth required?
Answer: Option D
:
D
Given that the area of the blue cloth = 110ofareaofyellowcloth
⇒110of60cm2=6cm2
Since area of the total cloth = Area of the yellow cloth + Area of the blue cloth + Area of the red cloth required,
⇒Area of the red cloth required = Area of the total cloth-Area of the yellow cloth - Area of the blue cloth
⇒80cm2−60cm2−6cm2=14cm2
Thus, area of the red cloth =14cm2
