Mr. Chen is painting one wall of a room in his attic. He needs to determine the area of the wall so he will know how much paint he will buy. The drawing below shows the dimensions of the wall. If one quart of paint will cover 16 square centimeters, how many whole quarts will Mr. Chen need to buy?

He will need to buy whole quarts.

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
