Answer 1

Answer:1st d

Please mark as brainliest

2nd question options wrong

3rd d

8th c

7th c

6th d

5th b

4th b

Step-by-step explanation:

Answer 2

1) d) an equilateral triangle

2) d) rectangle

3) c) 20:28

5/7 × 4/4 = 20/28

4) b) ad = bc

5) c) becomes one fourth

Consider square of side x

Then area = x²

Now if it is halved , x/2

Area of square = x²/4

= Area of first square /4

6) none of these. The answer is 103.09 cm²

2πr = 36

r = 18/π

Area of circle ,

πr² = π× 18/π ×18/π

Area = 1134/ 11 = 103.09 cm²

7) c) 2y + 3 = 11

8) c) x/6 m

Hexagon contains 6 sides and all sides are equal.

So if perimeter is x m then side = x/6 m
