Question

find the area of colored square​

Answer 1

125 sq units

Step-by-step explanation:

Area of bigger square = 15*15=225

Area of 4 triangles = 1/2*10*5*4 = 100

Area of coloured square = 225-100 = 125 sq units

Answer 2

Answer: 90

Step-by-step explanation:

1. find the hyp of big triangle using pythagoras comes to 15.81

2. there are 2 parallelograms and rhe square is sandwiched between them.

3. the height of the paralleogram is the side of the colored square which is critical to compute area

4. area of the parallelogram = area of big square - area of 2 big triangles

5. 225 - 37.5 - 37.5 = 150

6. area of parallelogram = b x h

7. 150 = 15.81 x h

8. height or side of square = 9.49

9. area of square = 9.49 x 9.49 = 90 rounded
