Question

The length is not provided and need to find the shaded area

Answer 1

Answer:

Area: 98 in^2

Step-by-step explanation:

8-3=5

Triangle: a^2 + b^2 = c^2

a^2 + 5^2 = 13^2

a^2 = 169-25

a = sqrt 144

a = 12

Area: 16in * 8in = 128 in^2

Area rectangle - triangle

Area triangle: (bh)/2

(12*5)/2 = 30 in^2

128 - 30 = 98 in2

Answer 2

Answer:

Step-by-step explanation:

lower left triangle:  5^2 + x^2 = 13^2

x^2 = 144 => x = 12

So, area of triangle is : (5 * (12-4))*0.5 => 20

Shaded area: (8 *12) -20 => 96 -20
