Jennifer has a square bedroom. the area of her room is 144 ft2. what is the length of one side of jennifer’s room?
a 10 ft
b 12 ft
c 18 ft
d 36 ft

B.) 12 ft

Step-by-step explanation:

A square's sides are all the same: meaning, every side MUST be the same length. Then, all we have to do is find the square root of 144, which is 12.

To check this, we need to multiply the length times the height. If it equals 144, it is correct.

12 x 12 = 144

Hope I explained this well enough! If this seems confusing, or if you haven't learned square roots yet, you can always just try multiplying down the list of available choices to see what equals 144 c:

( 10 x 10 = 100, 12 x 12 = 144, 18 x 18 = 324, 36 x 36 = 936)

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
