Here is a shape made from a rectangle and a triangle.
NISA [10]

Answer:

Area of shape =  187 cm²

Step-by-step explanation:

Given:

Length of rectangle = 15 cm

Width of rectangle = 9 cm

Height of triangle = (22-9) cm = 13 cm

Base of triangle = (15-7) cm = 8 cm

Find:

Area of shape

Computation:

Area of shape =  Area of rectangle  + Area of triangle

Area of shape =  (l)(b) + (1/2)(b)(h)

Area of shape =  (15)(9) + (1/2)(8)(13)

Area of shape =  135 + 52

Area of shape =  187 cm²

1 pint= 1/8 gallon. How many pints are there in 2/3 gallon.
FrozenT [24]

gallon = pint *0.125

gallon = pint / 8
0.125+0.125+0.125+0.125+0.125+0.125+0.125+0.125+0.125+0.125+0.125+

0.125+0.125+0.125+0.125+0.125 = 2

16 would be the answer I believe, maybe I'm wrong, double check.
