Sharon has a piece of cloth of area 170 sq. cm; can she make a square handkerchief of length 12 cm

Yes

Step-by-step explanation:

First we have to get the area of the square when the length is 12cm. We know a square has equal sides so we can simply do l * l to get the area.

12 * 12 = 144.

Let's compare this to 170.

170 > 144, so yes we will have enough to make a 12 by 12 handkerchief :)

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.
