(image) The figure below is an isosceles triangle surmounted by a semi-circle. Find the area of the entire region.
S_A_V [24]

Answer:

12.53

Step-by-step explanation:

∠BCA = (180°-40°)/2 = 70°

Laws of Sines: CA/sin 40° = AB/sin 70° = 5/sin 70°

CA = 5/sin 70° * sin 40° = 3.40

area of semicircle CA = (3.1416 * 1.70²) / 2 = 4.54

By Heron's Formula, area of triangle ABC:

1/4 √(a+b+c) (a+b-c) (b+c-a) (c+a-b) = 1/4 * √13.4*3.4*3.4*6.6

                                                          = 7.99

Entire region area = 4.54 + 7.99 = 12.53

HELP ASP PLS I WILL GOVE BRAINIST PLS PLS PLS HELPPPP picture below
belka [17]

We can solve this problem in three steps.

<u>1) find the area of the square</u>

a=lw\\\\a=(7.5)(6)\\\\a=45ft^{2}

<u>2) find the area of the triangle</u>

a=\frac{1}{2}bh\\\\a=\frac{1}{2} (6)(4)\\\\a=12ft^{2}

<u>3) add the areas together</u>

a=45+12

<em>a = 57 ft²</em>
