The first one is congruent by ASA. The second does not have to be congruent, we don’t know enough.
Answer:
26 1-foot squares of silver paper.
Step-by-step explanation:
The dimensions of the bulletin board are 6.5 feet by 4 feet.
To determine how many squares of silver paper she needs to but, we first determine the area of the bulletin board.
Area of the board =6.5 X 4= 26 Square feet
Therefore, Mrs Golden needs to buy <u>26 1-foot squares of silver paper.</u>
There will be <u>no pieces left over</u> as there is no decimal or fractional value in the area of the bulletin board.
Area of big rectangle =8x7=56cm²
area of small rectangle =5x4=20cm²
hence area of shaded region=56-20=36cm²
None, because you must add the 2 shortest sides and the total must be greater than the longest side in order to be able to make a triangle.
