.7+.55-.3=1.25-.3=.95=95/100=19/20 thats the first option
Answer:
Area of the figure = 36 in²
Step-by-step explanation:
Area of the given composite figure = Area of the rectangle ABCE - Area of triangle CDE
Area of rectangle ABCE = Length × Width
= AB × AC
= 6 × 8
= 48 in²
Area of triangle CDE = ![\frac{1}{2}(\text{Base})\times (\text{Height})](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%28%5Ctext%7BBase%7D%29%5Ctimes%20%28%5Ctext%7BHeight%7D%29)
= ![\frac{1}{2}(6)(4)](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%286%29%284%29)
= 12 in²
Now area of the composite figure = 48 - 12
= 36 square inch
