Find the area of the shaded region

40.5

Step-by-step explanation:

We need to find the area of both triangle and square. We then subtract the triangle from the square. Let's do it.

The area of the square is 9x9. This is 81 squared meters.

Triangle formula is 1/2 base x height. We know that base and height are both 9. 81/2 is 40.5.

We subtract now. 81-40.5=40.5

40.5 is the area of the shaded region.

40.5 square meters

Step-by-step explanation:

to find area of shaded region:

area of square minus area of triangle

A(square) = 9² or 81

A(triangle) = 1/2(9)(9) = 40.5

81 - 40.5 = 40.5

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)
