Answer:

80 square units

536.6 cm^{2}

Step-by-step explanation:

First one.

2 Trapezoids

A = \frac{(base_{1} +base_{2}) }{2} x h

A = \frac{10 + 6}{2} x 2

A = 16

One rectangle

A = b x h

A = 6 x 8

A = 48

Total Area = 16 + 16 + 48 = 80

Second one:

Two triangles:

A = \frac{(b)(h)}{2}

A = \frac{10(8.66)}{2}

A = \frac{86.6}{2}

A = 43.3

One large rectangle

A = b x h

A = 30 x 15

A = 450

Total Area = 450 + 43.3 + 43.3 = 536.6

It’s a positive slope, constant slope, and increasing function. Because it’s a straight line going diagonally to the top right, you know the slope is positive, constant, and the function is positive.
