180 ft²

Step-by-step explanation:

The figure is composed of 2 triangles and a rectangle between them

Calculate area of triangle on left

A = bh ( b is the base and h the perpendicular height ), thus

A = × 9 × 6 = 4.5 × 6 = 27 ft²

Area of rectangle = 12 × 9 = 108 ft²

Calculate the area of the triangle on the right

A = × 9 × 10 = 4.5 × 10 = 45 ft²

area of composite figure = 27 + 108 + 45 = 180 ft²

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
